Refresh text input on jQuery Mobile (themes)

I'd like to refresh in an input text after dynamically add the attribute "data-theme".

How can I do this?

I'd like that: http://jsfiddle.net/Sgrve/5/

If I click the "Change Theme", I 开发者_JAVA百科want to change the color of the input.

Data-theme attribute change but the color don't change.

Try running

$('#page_id').page('refresh');

or

$('#list_id').listview('refresh');

if it's inside a List.
