Changing container State from a component

Question

Hi, I try to change the state of an application from a button
inside a mxml component. I found a way for this by handling click
event inside the component and dispatch event to the container (see
the code below). But my problem is that any click is dispatched ! I
would like that only one button dispatch this event, or better :
calling a container's function from the button inside my component
! Is this possible ?
Thanks for your help
Here is a part of the container code :
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="
http://www.adobe.com/2006/mxml"
width="570" height="360" xmlns:local="*">
<mx:Script>
<![CDATA[
import flash.events.Event;
public function handleCloseEvent(eventObj:Event):void {
currentState='carte';
]]>
</mx:Script>
<mx:states>
<mx:State name="liste">
<mx:AddChild position="lastChild">
<local:liste_vin_region click="handleCloseEvent(event);"
id="fenetre">
</mx:AddChild>
</mx:State>
<mx:State name="carte"/>
</mx:states>
</mx:Canvas>
And the component code :
<mx:Canvas xmlns:mx="
http://www.adobe.com/2006/mxml"
width="514" height="300" xmlns:local="*">
<mx:Metadata>
[Event(name="click", type="flash.events.Event")]
</mx:Metadata>
<mx:Script>
<![CDATA[
import flash.events.Event;
// Redispatch event.
private function
handleCloseEventInternally(eventObj:Event):void {
dispatchEvent(eventObj);
]]>
</mx:Script>
<mx:states>
<mx:State name="liste"/>
</mx:states>
<mx:TitleWindow layout="absolute" left="10" top="10"
bottom="10" right="10" id="titlewindow1"/>
<mx:Button y="14" label="X" right="19" width="29"
click="handleCloseEventInternally(event);" id="button1"/>
</mx:Canvas>

Yes ! That's exactly what I need !
I've tried to do : this._parent like in Flash, but no
result...
Thanks for your help, parentApplication is right for me
