var models:Array = new Array();
models[0] = new Mod();
models[1] = new Mod();
models[2] = new Mod();
models[3] = new Mod();
var i:uint = 0;
var j:uint = 0;
for each (var obj:Mod in models)
{
	obj.buttonMode = true;
	obj.x = i;
	i += obj.width + 5;
	obj.__id = ++j;
	addChild(obj);
  obj.addEventListener(MouseEvent.CLICK, moveModel);
}
function moveModel(event:Event):void {
	trace(event.target.toString());
	trace(event.target.x);
	trace(event.target.__id);
}

По идее должно хватить =)
