javascript - Fullcalendar --- Add / change Optioions on the fly -

i have found in source code:

// function adding/overriding defaults function setdefaults(d) {     $.extend(true, defaults, d); } 

i added

fc.setdefaults = setdefaults; 

to have access function. try change options , render whole calendar them, nothing happens.

$.fullcalendar.setdefaults({    axisformat:"h:mm" }); $('#calendar').fullcalendar('render'); 

is there way / set options after calendar created?
