Browser/JQM not showing the updated content

Hi everyone,
I've created an app using JQuery Mobile. There are several checkboxes ( 3 persons), at the beginning all three checkboxes are enabled . When I disable the first person and submit the form (button "Speichern"), the expected result is, that the disabled person shows up disabled as the last checkbox. But instead of this, the person remains enabled and an other (the third one) gets disabled . Hitting Ctrl+F5, the page gets reloaded and everything looks nice as expected.

You can do your tests at: kma.2fh.co/test1.php

The underlying PHP script is working correctly, as everything is working as expected if I do not include JQMobile. See here: kma.2fh.co/test2.php

Somehow it could be some issue with caching etc, I already have tried some meta tags, but no success so far. Could you please help on that with any idea? Or does it work on your site without any manual page reload (Ctrl+F5)?

JQ Ver. 1.11.1/JQM Ver. 1.4.5/Browser FF 35.0.1

regards,
Janosh
