title: daterangepicker apply buttom not working properly
body: <p>I am using daterangepicker please check my code here <strong><a href="http://jsfiddle.net/chinmay235/5ef2rqmq/1/" rel="nofollow">JSFIDDLE</a></strong></p>
  
  <p>I have set default date </p>
  
  <pre><code>"endDate": "08/03/2015",
  "endDate": "08/03/2015",
  </code></pre>
  
  <p>And I have set an <code>alert()</code> for checking my code is working or not.</p>
  
  <pre><code>alert("New date range selected: '" + start.format('YYYY-MM-DD') + "' to '" + end.format('YYYY-MM-DD') + "'"); 
  </code></pre>
  
  <p>When I am clicking on <code>book_date</code> textbox range calendar is appearing.
  If i am changeing any date and clicking apply button its working fine. My <code>alert()</code> box is showing perfect. But when i click apply button without change any date. That time <code>alert()</code> box is not showing.</p>
  
  <p>Also <code>book_date</code> is getting default date after clicking textbox and click anywhere in the page. So i don't want to put any default date without cilcking particular date. textbox should be blank while clicking ouside of calendar.</p>
  
  <p>My Edited Code:</p>
  
  <pre><code>$('#book_date').on('apply.daterangepicker', function(ev, picker) {
      alert("New date range selected: '" + picker.startDate.format('YYYY-MM-DD') + "' to '" + picker.endDate.format('YYYY-MM-DD') + "'");
  });
  </code></pre>
  
  <p>My textbox Calendar getting default value if i am not select any and clicking outside anywhere of the page.</p>
