Still struggling with event dispatching

1

Can anyone please explain me why the dispatched event is not captured in this code?

The idea here was to notify all instances of a class when you click on one of them.



package sample{

    import flash.events.EventDispatcher;
    import flash.events.MouseEvent;
    import flash.display.MovieClip;
    import flash.events.Event;

    public class labels extends MovieClip {

        var dispatcher:EventDispatcher = new EventDispatcher();

        public function labels() {
            this.buttonMode = true;
            this.addEventListener(MouseEvent.CLICK, butClick);
            this.addEventListener("bla-bla", capture);
        }

        public function butClick(e:MouseEvent) {
            dispatcher.dispatchEvent(new Event("bla-bla"));
            trace("clicked: " + e.currentTarget);
        }

        function capture(e:Event) {
            trace(e.currentTarget + ": one of us have been clicked!");
        }

    }

}

Thanks!
