Fullcalendar rerender events

Question

I'm trying to rerender removed elements on my calendar (Fullcalendar.io) but isnt working.

Here's the code:

        $("#check1").click(function(){
            if($('#check1').prop('checked')) {
                $("#calendar").fullCalendar('rerenderEvents', 'id1');
            } else {
                $("#calendar").fullCalendar('removeEvents', 'id1');
            }
        });
        $("#check2").click(function(){
            if($('#check2').prop('checked')) {
                $("#calendar").fullCalendar('rerenderEvents', 'id2');
            } else {
                $("#calendar").fullCalendar('removeEvents', 'astronomia');
            }
        });

I've tried refetchEvents, renderEvent, addEventSource, clientEvent and updateEvent none of them worked. How can I solve that?
