without mobile js - works, so, think, problem in jquery.mobile-1.3.2.min.js.

how fix it? thanks.

when using jquery mobile widgets, after page loaded , inserted dom, widgets enhanced. enhancement happens between pagecreate , pageinit events. if programmatically change items of widget after enhancement step, must trigger enhancement of widget. need call 'refresh' method on widget. because using selectmenu widget, after change of options have call refresh method in next way:

select.selectmenu('refresh');
