Sprite won't respond to custom event

Question

I've got an app where numerous Sprite objects are being placed on the stage, and then when an event occurs (mouse click most likely) I want all the Sprites to move, independently, based upon an algorithm that each Sprite has.  I can't get the Sprite objects to respond to the event; I get no errors, it's just that the right thing isn't happening, see my comments below in red.
Thanks!
Here's my Event class:
package {
        import flash.events.Event;
            public class MyCustomEvent extends flash.events.Event {
                public static const CONTROL_TYPE:String = "moveThem";
                public function MyCustomEvent( type:String, bubbles:Boolean = false, cancelable:Boolean = false ) {
                    super(type, bubbles, cancelable);
Here's  my main:
import MyCustomEvent;
import flash.events.EventDispatcher;
import flash.events.Event;
import flash.display.Sprite;
var arr:Array = new Array();
for (var i:int = 0; i < 10; i++) {
    var c:Sprite = new Sprite();
    c.addEventListener(MyCustomEvent.CONTROL_TYPE, doSomething);
    c.graphics.beginFill(Math.random() * 0xffffff);
    var myX:int = Math.random() * 500;
    var myY:int = Math.random() * 500;
    c.graphics.drawCircle(myX, myY, 5);
    addChild(c);
    arr.push(c);
function doSomething(e:Event):void {
    trace("Sprite heard event");  // this does NOT occur
addEventListener(MouseEvent.CLICK, mouseClick);
function mouseClick(e:Event):void {
    trace("click"); // this occurs
    dispatchEvent(new MyCustomEvent(MyCustomEvent.CONTROL_TYPE));

Is it that you are writing your main codse on timeline?
I don't see a main class there...
Also,
If you are just calling code on maintimeline then the event won't be dispatched relative to the sprite
see below:
import MyCustomEvent;
import flash.events.EventDispatcher;
import flash.events.Event;
import flash.display.Sprite;
var arr:Array = new Array();
for (var i:int = 0; i < 10; i++) {
    var c:Sprite = new Sprite();
    c.addEventListener(MyCustomEvent.CONTROL_TYPE, doSomething);
    //Added listener to Sprite object c
    c.graphics.beginFill(Math.random() * 0xffffff);
    var myX:int = Math.random() * 500;
    var myY:int = Math.random() * 500;
    c.graphics.drawCircle(myX, myY, 5);
    addChild(c);
    arr.push(c);
function doSomething(e:Event):void {
    trace("Sprite heard event");  // this does NOT occur
addEventListener(MouseEvent.CLICK, mouseClick);
function mouseClick(e:Event):void {
    trace("click"); // this occurs
    dispatchEvent(new MyCustomEvent(MyCustomEvent.CONTROL_TYPE));
/*the line above is called as this.dispatchEvent(new MyCustomEvent(MyCustomEvent.CONTROL_TYPE));
    and here this refers to main time line rather than c. It should be called like
c.dispatchEvent(new MyCustomEvent(MyCustomEvent.CONTROL_TYPE));
You should somehow dispatch the event with relation to the same Sprite which was created earlier. What you are looking for can be done as below in your case:
for(var i = 0; i<arr.length; i++)
     arr[i].dispatchEvent(new MyCustomEvent(MyCustomEvent.CONTROL_TYPE));
