title: jquery fullcalendar event filtering
body: <p>Is there any method to dynamic filter events on client side in fullcalendar?
  When I get events from server (json_encoded) I assign my own parameter "school_id" to every event.
  After fullcalendar is ready, I want to dynamic filter events with "select".</p>
  
  <p>I add "select" element on page like this:</p>
  
  <pre><code>&lt;select id='school_selector'&gt;
        &lt;option value='all'&gt;All schools&lt;/option&gt;
        &lt;option value='1'&gt;school 1&lt;/option&gt;
        &lt;option value='2'&gt;school 2&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>And in javascript code I add:</p>
  
  <pre><code>jQuery("#school_selector").change(function(){
      filter_id = $(this).val();
      if (filter_id != 'all') {
          var events = $('#mycalendar').fullCalendar( 'clientEvents', function(event) {
          if((filter_id == 'all') ) {
              return true;
          }else{
                  //what I need to write here to dynamic filter events on calendar?
          });
      }
   });
  </code></pre>
  
  <p>But it's does not work.
  Any help will be great.thanks. </p>
