title: Find out when full calendar loaded events
body: <p>I have a fullCalendar widget created somewhere. I cannot change the code that initialize it. So I cannot add any callbacks in the first call.</p>
  
  <p>Anything like this:</p>
  
  <pre><code>$(elem).fullCalendar({
     complete: function () {
       ...
     }
  })
  </code></pre>
  
  <p>Actually creates a new fullCalendar instead of modifying the actual fullCalendar to change/add the complete callback.</p>
  
  <p>Is there an other way to find out when events are loaded I was thinking about polling <code>clientEvents</code> but I realize that I could have no events in one month so I cannot expect the array to always have something in it.</p>
  
  <p>By the way, it's fullCalendar 1.6. </p>
