howto atach properties to dynamic created moviclips - actionscript-3

Question

Hi I try to get acces a property by click on a dynamic created Moviclip.
function finishLoading(evt : Event):void {
// Handle XML Settings
XML.ignoreComments=true;
XML.ignoreWhitespace=true;
// Attach XML Data into XML Var
fXML=new XML(evt.target.data);
// Iterate XML response and build Preview List
for (var i:Number=0; i<fXML.mov.length(); i++) {
var sTmpTitle=fXML.mov[i].mov_title.text();
var sTmpSrc=fXML.mov[i].mov_src.text();
var sTmpThumb=fXML.mov[i].mov_thumb.text();
var sTmpOrder=parseInt(fXML.mov[i].mov_list_order.text());
var iPosY:Number = (sTmpOrder!=1)?(sTmpOrder-1)*105:0;
var sTmpLoader:Loader = new Loader();
sTmpLoader.load(new URLRequest(sTmpThumb));
var oTmpMc:MovieClip = new MovieClip();
oTmpMc.addChild(sTmpLoader);
oTmpMc.y=iPosY;
oTmpMc.x=0;
oTmpMc.mov_src = sTmpSrc;
oTmpMc.addEventListener(MouseEvent.CLICK, function()
{
trace(this.mov_src);
});
mc_slider.addChild(oTmpMc);
}
}
Creating the MOVIECLPIP and handle event is working well but I dont know hw I can get access on the property mov_src by click on the clip.
What´s to do to get this working.
Thank
Ben

First of all, you shouldn't add dynamic properties to movieclips, it's a bad habit from AS2. You should extend the MovieClip class and add the properties you want. Anyway, you can do what you want to do by externalizing your callback :
...
oTmpMc.addEventListener(MouseEvent.CLICK, onClipClicked);
mc_slider.addChild(oTmpMc);
}
private function onClipClicked(e:Event):void
{
var clip:MovieClip = e.currentTarget as MovieClip;
trace(clip.mov_src);
}
