i'm having a little problem. My push panels on this site are not  running   as they should.

Here is the link:  http://www.glaserarbeiten.info/mobilewebsite/

Im pretty new to jquery mobile. I  thought i could get some help here.

If you click the panel, and go to another page and activate the push panel there again and switch back to e.g. home the panel is not sliding out sometimes. I tried it in Chrome, Firefox and Safari + Samsung Galaxy SII standard browser.
