I am using a custom calendar datepicker from the following link

http://sajanmaharjan.com.np/nepali-datepicker/

This datepicker seems to be working fine but I am failing to display the date-picker by default when a page loads.

we can display the calendar of jquery with $('#id').datepicker('show'), however above datepicker doesn't have any such functionality. it can only be accessed only when a user clicks on textbox.

I tried initializing datepicker with an Id of an element

<div id="nepaliDate"></div>

     $(function(){
          $('#nepaliDate').nepaliDatePicker();
     });

Above code doesn't display calendar on page load.

The only code that works is with input type="text" and when we click on the textbox

     <input type="text" id="nepaliDate"/>
     $(function(){
          $('#nepaliDate').nepaliDatePicker();
     });

Could any please help me in knowing how can I display the calendar on document.ready or window.load?

Thanks
