      navigator.notification.confirm(
          'Are you ready to submit?', // message
          function(buttonIndex) {
              onConfirm(buttonIndex);
          },
          'Confirmation', 'Yes,No' // buttonLabels
      );
  }
  
  function onConfirm(buttonIndex) {
      if (buttonIndex === 1) {
          didClickSubmitButton();
      } else if (buttonIndex === 2) {
          return false;
      }
