Subpages not loading via AJAX in A4

Subpages not loading via AJAX in A4

Hi there,

i am currently developing a mobile webapp for my company.

In A3 it all worked fine (except the collapsible scrolling problem which is solved now).

In A4 i have a problem with the loading of the subpages.
They are always loaded with a regular request, not via ajax.

You can see my Test-Webapp here: http://mobile.mdx.itobe.de/go.to/modix/now/test.html
On this Mainpage the whole html structure with the root/home page-container is delivered.
The Subpages are only responsed with the specific page-container.

If you click on a Testlink (2-4) you can see that there is no ajax-loading and no transition.

Is this a known problem or am i just missing some new configuration and default settings :D?

Thanks in advance. Greets.
