I just started using jQuery Mobile 1.2.0 in a small project. I am using 4 select boxes with multiple option activated and native popups disabled (I like the fancy ones of JQM). If the elements on the first box are selected, I dynamically populate the second box and so on. 

Currently the behavior of the JQM select is to update the original select as soon the item is selected. It is quite a bad idea to start an Ajax request on each item selection to update the second box. It would be great if there is an option to update select only one time as soon as the popup closes.
