data-add-back-btn does not show a back button

Question

I have a simple jQuery mobile site with three pages in it. In every page's div I've added

data-add-back-btn="true"

Still on none of the pages (not even on the sub-pages) a back button appears. Is there some trick to this?

Answer 1

As of jQuery Mobile 1.4, data-add-back-btn="true" should be added to header div not page div.

<div data-role="page">
  <div data-role="header" data-add-back-btn="true">
    <h1>Header</h1>
  </div>
</div>
