title: fullcalendar dow is not working
body: <p>I have tried different settings, but nothing seems to work, I need to repeat events on calendar, like all Sundays, Tuesdays. Here is my code:</p>
  
  <pre><code> $('#appointment_calendar').fullCalendar({
  
          header: {
              left:   'prev',
              center: 'today',    
              right:  'next'
          },
          events: [{
              title:"My repeating event",
              start: '10:00', 
              end: '14:00', 
  
              dow: [ 1, 4 ] 
          }],
      });
  </code></pre>
  
  <p>Have tried removing/adding tittle, start, end, ranges, nothing seems to works.</p>
