title: Highlighting the selected date in FullCalendar
body: <p>I'm trying to make the selected day in FullCalender.io highlighted (similarly to how the current day is).</p>
  
  <p>Following <a href="https://stackoverflow.com/questions/19783833/fullcalendar-highlight-a-particular-day-in-week-view">FullCalendar - Highlight a particular day in week view</a> I've tried the following, which basically re-renders the calendar on a click, and highlights the cell who's date matches the clicked date .</p>
  
  <pre><code>    dayRender: function(date, cell)
      {
          var moment = $('#calendar').fullCalendar('getDate');
  
          if (moment.get('date') == date.get('date'))
          {
              $(cell).addClass('fc-state-highlight');
          }
          else
          {
              $(cell).removeClass('fc-state-highlight');
          }
      },
      dayClick: function (date, allDay, jsEvent, view) {
          $('#calendar').fullCalendar('render');
      },
  </code></pre>
  
  <p>But it's not doing anything. :-( </p>
