Change label of a NativeMenuItem - apache-flex

Question

I'm experimenting with Adobe AIR and Google Maps API in Flex Builder. The question is, i'm making a NativeMenu, and was wondering, how can I change the label of the "Fullscreen" item to "Exit fullscreen" when the stage is in fullscreen?
If you see any thing in the code that could/should be written better, please let me know ;)
Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication
xmlns:mx="http://www.adobe.com/2006/mxml"
layout="absolute"
height="600"
width="700"
minHeight="100"
minWidth="100"
showStatusBar="false"
title="Gmaps 0.002"
>
<maps:Map
xmlns:maps="com.google.maps.*"
id="map"
mapevent_mapready="onMapReady(event)"
width="100%"
height="100%"
url=""
key=""
/>
<mx:Button id="fullscreenButton" click="toggleFullScreen()"/>
<mx:Script>

in order to change a label into a NativeMenu, you can try this
yourNativeMenu.getItemAt(0).label="new_label";
where getItemAt(0) return the first item in the NativeMenu
