Interaction: Eventlistener and Displays objects

Question

I have two classes ( shown below after problem description),  the InteractiveStrategy and Filters classes.
The class InteractiveStrategy is the main class definition. In there I declare and instantiate two variables, updateData and filters.I also display
the lists mqList and sqList.
In the Filters class I have two methods, MainQuestions() and SubQuestions(mq:int).
The method MainQuestions() populates a list mqList with the main-questions and SubQuestion populates list sqList with the sub-questions. This means each main-question has a set of sub-questions associated with it. Thus whenever the main-question (via mqList) changes, the set of sub-questions must change also.
My attempt at accomplishing the above is shown in the skeleton code below.The MainQuestions() method dispatches an event called 'mqChanged' while the  filter.MainQuestions() listens for the event. However I have no idea of how to execute filter.SubQuestions(mainQuestion) with the newly selected mainQuestion so as to display the new set of sub-questions. Or is there a better way of doing this?
public class InteractiveStrategy{
     public var updateData:UpdateData;
     public var filter:ArrayFilter;
     public var mainQuestion:int=0;
     public function InteractiveStrategy(){
          updateData = new UpdateData(downloadScript, true,URLLoaderDataFormat.VARIABLES);
          updateData.addEventListener("dataLoaded", onCompleteDataUpdate, false, 0, true);
      private function onCompleteDataUpdate():void{
            filter = new Filter(updateData.questions);//Passes over the questions array to the Filters
            addChild(filter.MainQuestions());//Displays the list of Main Questions
            filter.MainQuestion().addEventListener("mqChanged", changed, false, 0, true);//Listen for changes in mqList
            addChild(filter.SubQuestions(mainQuestion)); //Displays the list of Sub Questions
public class Filters{
      private var mqList:List = new List;//of class List, AS3 component
      private var sqList:List = new List;
      private questionsArray:Array
      public function Filters(questions:Array){
           questionsArray = questions
      public function MainQuestions(){
            //Populate List, mqList
            bqList.addEventListener(Event.CHANGE, listListener);
      public function SubQuestions(){
            //Populate List, sqList
            sqList.addEventListener(Event.CHANGE, listListener);
      private function listListener(e:Event):void { //this listens to many other lists in th program.
            var list:List = e.target as List;
            switch(list) {
             case mqList:
                   trace("Main question changed");
                   dispatchEvent(new Event("mqChanged"))
                   break;
             case sqList:
                   trace("Sub question changed");
                   dispatchEvent(new Event("sqChanged"))
                   break;

Craig, I have re-written the question. I have renamed the Filters class to ArrayFilters.
I have two classes ( shown below after problem description),  the InteractiveStrategy and ArrayFilters classes.
The class InteractiveStrategy is the main class definition. In there I declare and instantiate two variables, freshData and filter. I also display the lists mqList and sqList.
In the ArrayFilters class I have two methods, MainQuestions() and SubQuestions(mq:int).
The method MainQuestions() populates a list mqList with the main-questions and SubQuestions(mq:int) populates list sqList with the sub-questions. This means each main-question has a set of sub-questions associated with it. Thus whenever the main-question (via mqList) changes, the set of sub-questions must change also.
My attempt at accomplishing the above is shown in the skeleton code below.The MainQuestions() method dispatches an event called 'mqChanged' while the  filter.MainQuestions() listens for the event. However I have no idea of how to execute filter.SubQuestions(mainQuestion) with the newly selected mainQuestion so as to display the new set of sub-questions. Or is there a better way of doing this?
public class InteractiveStrategy{
public var freshData:UpdateData;
public var filter: ArrayFilters;
public var mainQuestion:int=0;
public function InteractiveStrategy(){
freshData = new UpdateData(downloadScript, true,URLLoaderDataFormat.VARIABLES);
freshData.addEventListener("dataLoaded", onCompleteDataUpdate, false, 0, true);
private function onCompleteDataUpdate():void{
filter = new ArrayFilters(freshData.questions); //Pass on the questions array for filtering
addChild(filter.MainQuestions());//Displays the list of main questions
addChild(filter.SubQuestions(mainQuestion)); //Displays the list of Sub Questions
//Here is my trouble area:
filter.MainQuestions().addEventListener("mqChanged", onMqChange, false, 0, true);//Listen for changes in mqList
function onMqChange():void{
//Update and display the sub questions
            addChild(filter.SubQuestions(mainQuestion)); //Displays the list of Sub Questions
public class ArrayFilters{
private var mqList:List = new List;//of class List, AS3 component
private var sqList:List = new List;
private questionsArray:Array;
public function ArrayFilters (questions:Array){
questionsArray = questions
public function MainQuestions(){
//Populate List, mqList
bqList.addEventListener(Event.CHANGE, listListener);
public function SubQuestions(){
//Populate List, sqList
sqList.addEventListener(Event.CHANGE, listListener);
private function listListener(e:Event):void { //this listens to many other lists in the program.
var list:List = e.target as List;
switch(list) {
case mqList:
trace("Main question changed");
dispatchEvent(new Event("mqChanged"));
break;
case sqList:
trace("Sub question changed");
dispatchEvent(new Event("sqChanged"));
break;
