Need some help, with fullcalendar business hour update.

My code :

```
$.each(json_resource, function(index,value){

  var businessHours = { 
    dow: [ value.dow ], 
    start: value.start, 
    end: value.end 
  }

  // GET RESOURCE OBJECT
  var resourceObject = $('#calendar').fullCalendar( 'getResourceById', value.resourceId );

  // ADD NEW BUSINESS WORKING HOUR
  resourceObject.businessHours = businessHours;

  // UPDATE HOURS
  $('#calendar').fullCalendar( 'option', 'resources', resourceObject);

});

```

The problem is **$('#calendar').fullCalendar( 'option', 'resources', events);** it freeze windows for some seconds. Maybe there is another solution for updating resource business hours ?
