ActionScript 3 and dynamic masks

Question

I have a MovieClip container that serves as the content area that I need to mask. When I create a mask inside this container using the form, I cannot interact with the contents of other containers that I create here, for example, buttons, etc.

This is what I do in the code (I left all imports, etc.):

class MyContainer extends MovieClip
{
   protected var masker : Shape = null;
   protected var panel : MyPanel = null;

   public function MyContainer()
   {
      this.masker = new Shape();
      this.masker.graphics.clear();
      this.masker.graphics.beginFill( 0x00ff00 );
      this.masker.graphics.drawRect(0, 0, 1, 1);  // 1x1 pixel.
      this.masker.graphics.endFill();
      addChild( this.masker );

      this.panel = new MyPanel();  // has buttons and stuff.
      addChild( this.panel );

      this.mask = this.masker;
   }

   // called by it parent when the stage is resized.
   public function resize( width : Number, height : Number ) : void
   {
      // set the mask to half the size of the stage.
      this.masker.width  = width  / 2;
      this.masker.height = height / 2;

      // set the panel to half the size of the stage.
      this.panel.resize( width / 2, height / 2);
   }
}

(Shape) , , MyPanel. MyPanel, / . , ​​ , ( ).

/ MyPanel?
