title: Ensure that end date is greater than start date and in the proper range
body: <p>I have a form with two date fields <code>start</code> date and <code>end</code> date.  The form has dynamically created rows each having these two date fields.</p>
  
  <p>I have set the start date and end date within a range using the <code>minDate</code> and <code>maxDate</code> features of <code>datepicker</code>.  It works except when I select the end date it should be greater than start date and it should also be within the date range.</p>
