Nope - Dynamic call of Function name

So I have something like this:

Code:
for (var i:int=0; i<menu_array.length(); i++) {
		var _callBackFuntion:String = "openMenu" + i;
		menu_array[i].addEventListener(MouseEvent.CLICK, _callBackFuntion);
	}
Your system of using:

Code:
menu_array[i].addEventListener(MouseEvent.CLICK, this[_callBackFuntion]);
does Not...
