title: fullcalendar - moved event again restore to old date when click prev/next
body: <p>I am using fullcalendar(v2.0.0) in my application. All events displaying from DB and user can drag and drop and updates events. Everything working fine except that <strong>dropped event again goes to old date when click on fullcalendar's next/prev button</strong>. </p>
  
  <p>check my fiddle <a href="http://jsfiddle.net/Manivasagam/3E8nk/1021/" rel="nofollow">http://jsfiddle.net/Manivasagam/3E8nk/1021/</a></p>
  
  <pre><code>$('#calendar').fullCalendar({
  events:"/FullcalendarProject/FullCalendarChecking" 
    // my events will be like this from DB [{title: 'Plants',start: '2015-05-18'}, {title: 'Animals',start: '2015-05-23'}]
  
  });
  </code></pre>
  
  <p>The exact problem is if i drag and dropped <strong>Plants</strong> event to 2015-05-20 then it moved to 2015-05-20 but if i click next/prev then again that moved event go back to 2015-05-18.</p>
  
  <p>Why this happen? How to fix this?</p>
