Answer 1

Try this, it should work:

$("#answer_1").button("refresh");

If that is also not working, try this

$("#answer_1").buttonMarkup();

EDIT: jsfiddle updated http://jsfiddle.net/androdify/xRTCu/4/ Use this:

 $("#answer_1 .ui-btn-text").text(data.mcq_1);

Why? Because jquery mobile adds a span around the button which has class="ui-btn-text"
