$.mobile.changePage() fail on PhoneGap/Cordova 1.5.0

changepage.js

(function() {
  $('#new-town').bind('pagebeforeshow', function(event) {
    $('a.my_link').bind('click', function(event) {
      $.ajax({
        contentType: 'application/x-www-form-urlencoded',
        type: 'POST',
        url: 'http://example.com/rest/sample',
        data: sample_params,
        success: function(data) {
          console.log('Ajax request is nice!');

          $.mobile.changePage("new_page.html", {
            reloadPage: true
          });

          console.log('changePage does not fail because this line is executed');
        }
      );

      event.preventDefault();
    });
  });
})();

It was my fault. "new_page.html" had an error. Blame on me!
