FullCalendar Re-Render-Ereignisse

Ich bin mit Fullcalendar integriert mit jQuery Mobile. Als ich versuchte, fügen Sie neue Ereignisse dynamisch, mit der folgenden Methode bei pageshow Ereignis verursacht es eine JavaScript-Ausnahme wie unten

Uncaught TypeError: Cannot call method 'empty' of undefined

Mein JavaScript-Code

    $('#myCalendar').live('pageshow',function(event){
            Newevents = [
                    {
                        title  : 'event1',
                        start  : '2012-11-24 01:00',
                        color:'red'

                    },
                    {
                        title  : 'event2',
                        start  : '2012-11-25',
                        end    : '2012-11-27'
                    },
                    {
                        title  : 'event3',
                        start  : '2012-11-28 12:30:00',
                        allDay : false //will make the time show
                    },
                    {
                        title  : 'event4',
                        start  : '2012-11-29 01:30:00',
                        allDay : false //will make the time show
                    }
                ];
        $('#calendar').fullCalendar('renderEvent',Newevents);
        $('#calendar').fullCalendar('rerenderEvents'); 

    });
