Доступ к кнопке из другого класса

[bogomol17]

Здравствуйте. Есть два класса StartPage и Game. В StartPage созданы кнопки. Есть ли возможность подключить к кнопкам слушатели из класса Game?

package components 
{
	import flash.display.Loader;
	import flash.display.LoaderInfo;
	import flash.display.MovieClip;
	import flash.display.SimpleButton;
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.events.MouseEvent;
	import flash.net.URLRequest;
 
	public class StartPage extends Sprite
	{
		private static const URL:String = "planeLib.swf";
		private static const START:String = "startPage";
		private static const BTN_PLAY:String = "btn_play";
		private static const BTN_RULES:String = "btn_rules";
		private static const BTN_about:String = "btn_about";
 
		private var contentLoaderInfo:LoaderInfo;
 
		private var startPage:MovieClip;
		public static var btn_Play:SimpleButton;
		public var btn_Rules:SimpleButton;
		public var btn_about:SimpleButton;
 
		public function StartPage()
		{
			addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
		}
		private function onAddedToStage(e:Event):void
		{
			removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
			var loader:Loader = new Loader();
			var request:URLRequest = new URLRequest(URL);
			loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadingComplete);
			loader.load(request);
		}
		private function onLoadingComplete(e:Event):void
		{
			contentLoaderInfo = e.target as LoaderInfo;
			var oStartPage:Class = contentLoaderInfo.applicationDomain.getDefinition(START) as Class;
			startPage = new oStartPage();
			addChild(startPage);
 
			var oPlay:Class = contentLoaderInfo.applicationDomain.getDefinition(BTN_PLAY) as Class;
			btn_Play = new oPlay();
			addChild(btn_Play);
			btn_Play.x = 547;
			btn_Play.y = 285;
 
			var oRules:Class = contentLoaderInfo.applicationDomain.getDefinition(BTN_RULES) as Class;
			btn_Rules = new oRules();
			startPage.addChild(btn_Rules);
			btn_Rules.x = 528;
			btn_Rules.y = 374;
 
			var oabout:Class = contentLoaderInfo.applicationDomain.getDefinition(BTN_ABOUT) as Class;
			btn_About = new oAbout();
			startPage.addChild(btn_About);
			btn_About.x = 520;
			btn_About.y = 465;
		}
	}
}

Код класса Game:

package
{
	import components.*;
 
	import flash.display.Sprite;
	import flash.events.MouseEvent;
 
	[SWF(width="800", height="600", frameRate="30")]
 
	public class Game extends Sprite
	{
		private var startPage:StartPage;
 
		public function Game():void
		{
			startPage = new StartPage();
			addChild(startPage);
			StartPage.btn_Play.addEventListener(MouseEvent.CLICK, traceFunc);
		}
		public function traceFunc(e:MouseEvent):void
		{
			trace("traceFunc");
		}
	}
}

Трэйс не работает. В чем может быть проблема?
