Object of this clas isn't garbage collected

I have a class which draws an object looking “window-like” on the stage, and i cant remove it from memory when i want to remove it. I think it missed some reference, but i don’t know where…

I construct it by calling this function:

 
{
...
ref.addEventListener(MouseEvent.CLICK,createContent);
...
}
private function createContent(event:MouseEvent):void {
var ref=root;
var content=new Content(ref.CONTAINER_OKNA,event.target.dane,390,270);
}

What I’m doing wrong?
