[ALOY-305] Event callbacks defined in markup are not working for Windows defined in NavigationGroup

REPRODUCTION: See code below. Ran on iPhone emulator. RESULTS: Click event (as well as others) is not executing the callback. WORKAROUNDS: Place "win2" inside it's own view and require it in the main view. Callbacks work. Also, using the $.win2.on or $.win2.addEventListener method work in the controller. index.xml:

<Alloy>
	<Window>
		<NavigationGroup id="nav" platform="ios,mobileweb">
			<Window id="win2" title="Red Window" backgroundColor="red" onClick="report" />
		</NavigationGroup>
	</Window>
</Alloy>

index.js:

function report (e) {
	Ti.API.info("event fired:" + e.type);	
}
$.index.open();
