```
var url:String;
var link:String;
var w:Number;
var h:Number;

url = loaderInfo.parameters.swfurl;
link = loaderInfo.parameters.link;

var request:URLRequest = new URLRequest(url);
var loader:Loader = new Loader();

loader.load(request);
addChild(loader);

loader.addEventListener(MouseEvent.CLICK, onClick);

function onClick(e:MouseEvent){
        trace('clicked');
}

```

This script show me external swf file. But MouseEvent.CLICK not working. Why?
