title: Jquery Fullcalendar selectHelper function not working
body: <p>According to the fullcalendar docs <a href="http://fullcalendar.io/docs/selection/selectHelper/" rel="nofollow">selectHelper</a> accepts a function:</p>
  
  <blockquote>
    <p>A function can also be specified for drawing custom elements. It will
    be given 2 arguments: the selection's start date and end date (Moment
    objects). It must return a DOM element that will be used.</p>
  </blockquote>
  
  <p>However this feature doesn't work. In fact nothing in the source code checks selectHelper for typeof function.</p>
  
  <p>Any ideas?</p>
