title: eventRender disappears in fullcalendar v5
body: <pre><code>Version : Fullcalendar-Scheduler v5 beta2
  </code></pre>
  
  <p>I tried eventRender like below in chrome:</p>
  
  <pre><code>document.addEventListener('DOMContentLoaded', function() {
      var calendarEl = document.getElementById('planningMix');
      var planningMix = $(calendarEl);
      var calendar = new FullCalendar.Calendar(calendarEl, {
          //...
          eventRender: function(info) {
              debugger
            },
          events: function(d, successCallback, failureCallback) {
             //...
          }
      });
  
      calendar.render();
  });
  </code></pre>
  
  <p>When I run this code, "debugger" didn't fired. <code>eventRender</code> has became another name in V5 ? </p>
