Adding a listener to a Child object

programming flash

I’ve created a container called “menu_container” and a child object called “hitbox” within it. When I add AddEventListener to the hitbox, it doesn’t call the specified function at all. Here is the code:


    // Create Container
    var menu_container:MovieClip = new MovieClip();
    addChild(menu_container);
 
    // Create hitBox
    var hitbox:Shape = new Shape();
    hitbox.name = "hitbox";
    hitbox.graphics.beginFill(0xFFFFFF);
    hitbox.graphics.drawRect(0, 0, 250, 100);
    hitbox.graphics.endFill();
    menu_container.addChild(hitbox);
 
    menu_container.getChildByName("hitbox").addEventListener(MouseEvent.MOUSE_OVER, moveIconMenu);
 
    function moveIconMenu(e:Event):void {
     trace("hello");
    }

Can anybody explain this? I’m completely stumped… Thanks for your time.
