เรียกใช้ฟังก์ชั่น Jquery ใน events ของ Fullcalendar ทำอย่างไร

<script>




function daysInMonth(month,year) {
    return new Date(year, month, 0).getDate();
}


function get_date(month,year){

	var year = year;
	var month = month;
	var getTot = daysInMonth(month,year); //Get total days in a month
	var weekend = new Array();   //Declaring array for inserting Saturdays
	var sun = new Array();   //Declaring array for inserting Sundays

  for(var i=1;i<=getTot;i++){    //looping through days in month
    var newDate = new Date(year,month,i)
    if(newDate.getDay()==0 || newDate.getDay()==0 ){   //if Sunday
        weekend.push(i);
    }
   
   return weekend;

}

}

	




 
       $('#calendar').fullCalendar({
      header    : {
        left  : 'prev,next today',
        center: 'title',
        right : 'month,agendaWeek,agendaDay'
      },
      buttonText: {
        today: 'today',
        month: 'month',
        week : 'week',
        day  : 'day'
      },
      events: [ 
   
      <?php foreach ($result as $index => $r) {  

      	$year = $r->year_quota;
      	if($r->month_quota == 10 || $r->month_quota == 11 || $r->month_quota == 12) {$month = $r->month_quota;}
      	else{$month = '0'.$r->month_quota ;}   ?>
      	
	weekend = get_date($month,$year);   // <------ ตรงนี้ที่เขียนเรียกใช้ฟังก์ชัน 
 
 	
 	{
      id: 'a',
      title: '<?php echo  $r->balance_quota; ?>',
      start: '<?php echo $r->year_quota.'-'.$month.'-'   ?>',
