[TIMOB-13564] BlackBerry : We get same index for 'OK' & 'Cancel' button on an alert dialog

Description: 1. Create an app for BB 2. Replace the code in the app.ja with the following code:

Ti.API.info('running');
 
var win = Ti.UI.createWindow({backgroundColor: 'red'});
win.open();
 
function showAlert() {
    Ti.API.info('opening alert...');
    var alert1 = Ti.UI.createAlertDialog({
        title: 'Click a button...'
    });
    alert1.addEventListener('click', function(e) {
        alert('index = ' + e.index);
    });
    alert1.show();
}
 
setTimeout(showAlert, 2000);

2. Build & run on BB device/simulator 3. The app launches 4. You will get an alert dialog qith a dialog 'click a button' 5. After taping on OK 0r Cancel button on the first alert dialog you will get another alert dialog with the index of the tapped button Actual Result: 1.Notice that tapping on both OK or Cancel gives us the same index i.e '0' Expected Result; 1. Both the OK & Cancel buttons should not have same index.
