Need help with custom event from Main class to an unrelated class.

Question

Hey guys,
I'm new to Flash and not great with OOP.  I've made it pretty far with google and lurking, but I've been pulling my hair out on this problem for a day and everything I try throws an error or simply doesn't hit the listener.
I'm trying to get my Main class to send a custom event to an unrelated class called BigIcon.  The rest of the code works fine, it's just the addEventListener and dispatchEvent that isn't working.
I've put in the relevant code in below.  Let me know if anything else is needed to troubleshoot.  Thank you!
Main.as
package
    import flash.display.MovieClip;
    import flash.events.MouseEvent;
    public class Main extends MovieClip
        var iconLayer_mc:MovieClip = new MovieClip();
        public function Main()
            Spin_btn.addEventListener(MouseEvent.CLICK,fl_MouseClickHandler);
            addChildAt(iconLayer_mc,0);
            placeIcons();
        function placeIcons():void
            var i:int;
            var j:int;
            for (i = 0; i < 4; i++)
                for (j = 0; j < 5; j++)
                    //iconString_array has the names of illustrator objects that have been converted to MovieClips and are in the library.
                    var placedIcon_mc:BigIcon = new BigIcon(iconString_array[i][j],i,j);
                    iconLayer_mc.addChild(placedIcon_mc);
        function fl_MouseClickHandler(event:MouseEvent):void
            dispatchEvent(new Event("twitchupEvent",true));
BigIcon.as
package
    import flash.display.MovieClip;
    import flash.events.Event;
    import flash.utils.getDefinitionByName;
    public class BigIcon extends MovieClip
        private var iconImage_str:String;
        private var iconRow_int:int;
        private var iconColumn_int:int;
        public function BigIcon(iconImage_arg:String, iconRow_arg:int, iconColumn_arg:int)
            iconImage_str = iconImage_arg;
            iconRow_int = iconRow_arg;
            iconColumn_int = iconColumn_arg;
            this.addEventListener(Event.ADDED_TO_STAGE, Setup);
        function Setup(e:Event)
            this.y = iconRow_int;
            this.x = iconColumn_int;
            var ClassReference:Class = getDefinitionByName(iconImage_str) as Class;
            var thisIcon_mc:MovieClip = new ClassReference;
            this.addChild(thisIcon_mc);
            addEventListener("twitchupEvent", twitchUp);
        function twitchUp(e:Event)
            this.y +=  10;

You should be getting an error for the Main.as class due to missing a line to import the Event class...
import flash.events.Event;
My apologies, I should attempt to compile my example code before I ask for help...
Alright, this compiles, gives me no errors, shows my 'book' and 'flowers' icons perfectly when ran, and prints 'addEventListener' to the output window as expected.  I get no errors when I press the button, 'dispatchEvent' is output (good), but the 'twitchUp' function is never called and 'EventTriggered' is never output. 
How do I get the 'twitchUp' event to trigger?

                for (j = 0; j < 3; j++)
                    if (Math.random() > .5)
                        //'flowers' is the name of an illustrator object that has been converted to a MovieClip and is in the library
                        iconString_array[i][j] = "flowers";
                    else

                    var placedIcon_mc:BigIcon = new BigIcon(iconString_array[i][j],i*50,j*50);
                    iconLayer_mc.addChild(placedIcon_mc);
        function fl_MouseClickHandler(event:MouseEvent):void
