jQuery Mobile: change/switch theme on listview data-split-icon -

i have split listview (with collapsible set) in jquery mobile (jqm). can see here on jsfiddle.

i want split icon act checkbox. icon has default data-theme="c" grey , want change data-theme b on click, icon color should change blue.

i tried different solutions change data-theme , found several more or less (more less) working solution. best simple jqm code $(this).buttonmarkup({theme: 'b'});, but, changing data theme way dont change color of icon, change color of background, can try in mentioned jsfiddle.

normaly data-theme on split listview, affect icon, when changed way, affects icons background. want change icon, not background , cannot find way that. wrong selector or kind of bug.

what think?

add below code.

demo

$(this).find('span.ui-btn').buttonmarkup({    theme: 'b' }); 

and

$(this).find('span.ui-btn').buttonmarkup({    theme: 'c' }); 

as span.ui-btn holds icon , its' style.
