Setting a Calendar event on a android device

Hello,

I'm using Titanium Studio, build: 3.2.1, and my operating system is Windows 8. I have an android alloy mobile application project. I need to set a calendar event on the calender of the device I tried the example in the appcelerator documentation it doesn't give me an error but it don't set an event in the calendar.

Here is my code:

var calendars = Ti.Android.Calendar.selectableCalendars;
        var names =[];
        for (var i = 0; i<calendars.length; i++) {
            names.push(calendars[i].name);
        }
 
        var calendarDialog = Titanium.UI.createOptionDialog({
            title: 'Select a Calendar',
            options: names,
            cancel:1
        });
        calendarDialog.addEventListener('click', function(e){
            var ci = e.index+1;
            var calendar = Ti.Android.Calendar.getCalendarById(ci);
 
            var eventBegins = new Date(2014, 6, 11, 10, 50, 0);
            var eventEnds = new Date(2014, 6, 11, 11, 0, 0);
            var hasReminder = true;
            var details = {
                title: 'i m testing',
                description: 'message',
                begin: eventBegins,
                end: eventEnds,
                hasAlarm:true,
                allDay:true
            };
 
            var event = calendar.createEvent(details);
 
            if (hasReminder)
            {
                var reminderDetails = {
                    minutes: 10,
                    method: Ti.Android.Calendar.METHOD_ALERT
                };
 
                event.createReminder(reminderDetails);
                alert('Event was created!....');
            }
 
            alert('Event was created!');
        });
        calendarDialog.show();
