How to access jEditable DatePicker options (onSelect, minDate, maxDate)

I am using jEditable together with jQuery DatePicker. I am trying to do validation for a date range. For example, if 1st June 2010 is selected in the startDate field, the user cannot select dates before 1st June 2010 in the endDate field and vice versa.

All of the other codes are working except the validation part. What I understand is that the full version of jQuery-ui DatePicker is included in the jEditable version but I do not know how to use it.

This is the DatePicker I am using: https://github.com/qertoip/jeditable-datepicker/tree/master/src

Sample Demo of DatePicker plugin: http://thesingularity.pl/jeditable-datepicker-demo/

My script

  $( '#startDate' ).editable('AppUpdateServlet',{
  indicator : '<img src="images/indicator.gif">',
  type: 'datepicker',
  datepicker: {
    dateFormat: 'dd/mm/yy',
    //minDate: '+1w'            (this is working)
    onSelect: function() {
       //the alert is working
       //alert("working");

       //not working
       $('#endDate').datepicker('option', {minDate: $(this).datepicker('getDate')});

     }
  }
});


$( '#endDate' ).editable('AppUpdateServlet',{
  indicator : '<img src="images/indicator.gif">',
  type: 'datepicker',
  datepicker: {
    dateFormat: 'dd/mm/yy',
    onSelect: function() {
    //not working
    $('#startDate').datepicker('option', {minDate: $(this).datepicker('getDate')});
    }
  }
});

HTML snippet

<span  id="startDate">
    <%=test.getStartDate()%>
</span>
<span  id="endDate">
    <%=test.getEndDate()%>
</span>

Not possible to reference to datepicker in jEditable. I have switched to using pure jQuery Datepicker to solve my problem.
