ActionScript 3.0 :: Add Eventlistener To A Child Movie Clip?

I have 2 movie clips, let's call them mcParent and mcChild. mcParent is a movie clip on the stage, and mcChild is a movie clip inside mcParent.I want to listen and execute a function (which is defined on the first frame of the stage), when mcChild is clicked. So I add the following script on the 1st frame of the main clip (stage):

Code:
mcParent.mcChild.addEventListener(MouseEvent.CLICK, clickChild);
function clickChild(e:MouseEvent):void
{
trace("click");
}

The clickChild function, however, is never called. So for whatever reason I am not receiving the event.

PS: I cannot add the event to mcChild. I know, that would be easy, but I need to have it this way, because when mcChild is clicked, I want to fade out mcParent (the clip that is on the stage).
