can't add an event listener to a mask AS3 Flash

New to AS3. Trying to do a simple mask exercise, but for some reason when I add event listener to 'myMask', the event doesn't trigger. I tried turning both 'myMask' and 'theMaskee' as sprites and movie clips, but no luck. It does trigger if I don't assign 'myMask' as a mask to 'theMaskee'. It also works if I add the listener directly to the stage, but eventually I want to put many things on the stage, and I'm afraid there will be conflict if it has to listen to the same event but perform several functions... especially if I need them one at a time. I looked through textbooks and the API and mask-related questions other people had, but I can't find anything relating to my specific situation. (this code is written directly in the timeline)

import flash.display.Bitmap;
import flash.display.BitmapData;
import flash.display.MovieClip;
import flash.display.Sprite;
import flash.sampler.NewObjectSample;
import flash.events.MouseEvent;


var temp = new backGround();
var myBG:Bitmap = new Bitmap(temp);
temp = new splashMaskee();
var theMaskee:Bitmap = new Bitmap(temp);


var myMask = new MovieClip();
myMask.graphics.beginFill(0x000000, 0);
myMask.graphics.drawRect(0, 0, 800, 600);
myMask.graphics.endFill();
myMask.cacheAsBitmap = true;
theMaskee.cacheAsBitmap = true;

theMaskee.mask = myMask;
addChild(myBG);
addChild(theMaskee);
addChild(myMask);

myMask.addEventListener(MouseEvent.CLICK, myMaskClick);
//stage.addEventListener(MouseEvent.CLICK, myMaskClick);

function myMaskClick(e:MouseEvent):void
{
    trace("click");
    myMask.graphics.beginFill(0x000000, 1);
    myMask.graphics.drawCircle(mouseX, mouseY, 30);
}

Thank you for taking the time

Do this:

theMaskee.addEventListener(MouseEvent.CLICK, myMaskClick);

And it should work. :)

Masks dont take any mouse/keyboard events as it is just a mask and not actually present in the display list.

You need to add the listener to theMaskee instead, not your mask. The mask in AS3 does not implement IEventDispatcher therefore can not catch and dispatch events.
