[TIMOB-957] Removing annotations from MapView breaks map evens

Hi,

I've outlined the issue on Q&A: http://developer.appcelerator.com/question/26471/mapview-click-event-does-not-fire-after-changing-annotations"> http://developer.appcelerator.com/question/26471/mapview-click-even....

Calling mapview.removeAnnotations seems to break the mapview 'click' event listener.

The following reproduces the issue:

//create two sets of pins
var pins1 = [
  Titanium.Map.createAnnotation({ latitude:37.390749, longitude:-122.081651, title:"pins1: A" }),
  Titanium.Map.createAnnotation({ latitude:37.74511, longitude:-84.38993, title:"pins1: B" }),
];
 
var pins2 = [
  Titanium.Map.createAnnotation({ latitude:37.390749, longitude:-122.081651, title:"pins2: A" }),
  Titanium.Map.createAnnotation({ latitude:37.74511, longitude:-84.38993, title:"pins2: B" }),
];
 
var mapview = Titanium.Map.createView({
    mapType: Titanium.Map.STANDARD_TYPE,
    animate:true,
    userLocation:false,
    annotations:pins1 //the initial setup, both pins will handle click events correctly
});
mapview.addEventListener('click', function(e) {
  Ti.API.log('- mapview click event : ' + e.clicksource);
});
Ti.UI.currentWindow.add(mapview);
 
 
//add a button to change the pins
var changePins = Titanium.UI.createButton({
    title:'change pins',
    style:Titanium.UI.iPhone.SystemButtonStyle.BORDERED
});
 
changePins.addEventListener('click',function() {
  //removing the initial pins and adding the seconds set - the second pind does not fire the clicked event 
    mapview.removeAnnotations(pins1);
    mapview.addAnnotations(pins2);
});
 
Ti.UI.currentWindow.setToolbar([changePins]);
