Could not close jt sage date picker after pick date

In my cordova app I am using the jt sage date picker (v 1.3.0) inside the popup

. Having opened a date picker in a popup using this SO answer , now there is a problem after picking a date that the datepicker cannot close.

 <input name="mydate" id="mydate" type="date" data-role="datebox" data-options='{"mode": "datebox", "useNewStyle":true}'/>

      

        
        
        
      

    

In the browser it works fine but in my device (nexus 7) it doesn't work.

Here is the FIddle Demo

EDIT:

Now I noticed another issue when writing the date or month in the picker and then again on the current date or month
