double click

Hi

I want to add a double clik detect to a movie clip which works fine and dandy if the movie clip jsut has gaprhics in it. However, i really could do with having th emovie clip also house other movie clips. But when i od this the double click doesnt seem to work. heres the cide bewlow:

var bubble:MovieClip;
bubble = new bubble_container();
this.addChild(bubble);
bubble.doubleClickEnabled = true;
bubble.addEventListener("doubleClick", doubleClick);

bubble.addEventListener("click", singleClik)

function doubleClick(event:Event){
trace("im double clikked");

}

function singleClik(event:Event){
trace("im single clikked");
}

is there a way of basically listenting for anything in bubble being double clicked?

thanks v much in advance
