I am passing data to be posted to the server. However, since the server accept XML and JSON, I have to specify the contentType just like a regular jQuery ajax request. This is what I tried but did not work:

1.     $.mobile.changePage('/Detail', {
           type: 'POST',
           contentType: 'application/json',
           data: {
               item: marker.item
           }
       });

Please allow an option to specify this.
