Event.CHANGE - bubbles or not?

Question

I have a little  Event propagation question;
Im using Fbuilder 3 testversion on XP and have flash player 10 installed.
Flax 3 API(at least that from http://livedocs.adobe.com/flex/3/langref/) says that the  flash.events.Event.CHANGE bubbles
butt wenn i debug the e:Event in the rb_selection function my debugger says it is does NOT.
So what now? Can anyone please explain this?
Following code (init is called on app's creationComplete
private function init():void {
    male.addEventListener(Event.CHANGE,rb_selection);
    female.addEventListener(Event.CHANGE,rb_selection); 
private function rb_selection(e:Event):void
    e;   
}//break point hier
]]>
</mx:Script>
<mx:VBox id="vb">
<mx:RadioButton groupName="gender"
                                    id="male"
                                    label="male"/>
<mx:RadioButton groupName="gender"
                                    id="female"
                                    label="female"/>
</mx:VBox>
</mx:Application>

Txn for help but i doesnt work for me. What I wont to do ist following. See the Code for main-app and  component:
main-app
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                xmlns:local="*"
                layout="vertical"
                applicationComplete="appComplete()">
    <mx:Script>
        <![CDATA[
            import mx.events.ItemClickEvent;
            private function appComplete():void
                comp.addEventListener(ItemClickEvent.ITEM_CLICK, ic_comp);
            private function ic_comp(e:ItemClickEvent):void{
                trace(e.toString())
                // HOW TO KNOW HIER WHICH ADIOBUTTON WAS CLICKED???           
        ]]>
    </mx:Script>
    <local:_RadioButtonGroup_comp id="comp"/>
</mx:Application>
component
<?xml version="1.0" encoding="utf-8"?>
<mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml"
          layout="vertical"
          width="300"
          height="200"
          creationComplete="creationCompleteHandler()">
    <mx:Script>
        <![CDATA[
            import mx.events.*;
            private function creationCompleteHandler():void
                rbg.addEventListener(ItemClickEvent.ITEM_CLICK, ic);
            private function ic(e:ItemClickEvent):void
                trace(e.target.selectedValue); //HIER I KNOW
                dispatchEvent(new ItemClickEvent(e.type, true));
        ]]>
    </mx:Script>
    <mx:RadioButtonGroup id="rbg"/>
    <mx:RadioButton groupName="rbg"
                    id="male"
                    label="male"/>
    <mx:RadioButton groupName="rbg"
                    id="female"
                    label="female"/>
</mx:Panel>
I can’t catch the dispached event from my component in my main-app.
In main app r target and currentTarget the same? So it simply doesn’t work. I expected to se the target as the radioButton,  but I see my component – probably because I redespached it ???
I found the solution is to define own event class, and then hoock the “old”-target as extra property wenn redespaching the event to the main app. That works.
But I ask my self – can it be the only way, Do I really have to write own event-class for every single Event that doesn’t bubble per default???
I mean, I understend the point of custom event-classes, one should use them when u need some “extra”-events which r not available in the API – but just because some not bubble?
There must be the other way? 
Please help, dont wona end up with hunderts of custom classes
