Referencing a button in a child swf

[KiKaL]

edit- Was able to fix it, this code worked

var imageReq:URLRequest = new URLRequest("travel-dump.swf");
var imageLoader:Loader = new Loader();
imageLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadHandler);
imageLoader.load(imageReq);

function loadHandler (event:Event){
var myClip:MovieClip = event.target.content;
addChild(myClip);

myClip.x = (stage.stageWidth - 975)/2;
myClip.y = (stage.stageHeight - 610)/2;




myClip.btnClose.addEventListener(MouseEvent.CLICK, btnCloseTravel);

function btnCloseTravel(event:MouseEvent):void {
    trace("worked");
}

}
