For the life of me I can't find an internet source that explains why this doesn't work. I know it's a scope problem but I know no other way around it and there must be a way to do it, I'm thinking.

I have a class. Inside this class I create a movieclip which I have a class variable link to. The movieclip is created on _root. When I click on this movieclip, I want it to call a function inside the class. Here's what it looks like.

Code:
class Whatever extends Movieclip {
  private var mc:MovieClip;

  public function Whatever() {
    this.mc = _root.createEmptyMovieClip("rootmc",_root.getNextHighestDepth());
    [code for drawing a square]
    this.mc.onPress = this.doSomething();
  }

  public function doSomething {
    [do something]
  }
In the above sample, when I click on the movieclip, the "doSomething" function is not called, obviously because the movieclip is on root and has nothing to do with the class. Is there a way to do what I want to do?
