        autoCloseDone:true, //default is true will close the popup when done is clicked.
        suppressTitle:false //Do not show the title if set to true
  });

  You can programatically trigger a close by dispatching a "close" event to it.

 $.query("body").popup({title:'Alert',id:'myTestPopup'});
 $("#myTestPopup").trigger("close");
