title: Parsleyjs Date Validation Doesn't work on Datepicker Events like Onchange
body: <p>I have a form with date picker input field which asks for value even after the date is chosen.</p>
  
  <p>note: This error doesn't come when i type the value.</p>

  <pre><code>&lt;input data-parsley-trigger="change" name="epa_date" required type="text" class="form-control" id="single_cal1" placeholder="(YYYY/MM/DD)"&gt;
  &lt;script&gt;
  $('#single_cal1').daterangepicker({
              singleDatePicker: true,
                minDate: moment(),
               format: 'YYYY/MM/DD',
              maxDate:  moment().add(15, 'days'),
              calender_style: "picker_1"
          }, function (start, end, label) {
              console.log(start.toISOString(), end.toISOString(), label);
          });
  &lt;/script&gt;
  </code></pre>
  
  <p>Edit Note: I have updated the script for date picker i use. 
  I am using Parsleyjs for all validations.</p>
