Problems w/ swipe gallery in demos jquerymobile.com

Problems w/ swipe gallery in demos jquerymobile.com

Hi.
I'm a newbie of this field but I'm trying to learn :)
I found a piece of code that works exactly as I like.
It's about navigation by means of a swipe event and it shows a photogallery. It's a very nice effect.
I found it in the demo pages of the jquery mobile site.
I followed the instruction, I checked the code viewing the page source of the given example and the source of the online pages. But it apparently doesn't work.
This is the link:

Can anybody help me?

Thank you very much in advance
