Accordion isn't triggering.

Accordion isn't triggering.

Hi, i'm trying to use accordion and it isn't triggering, it seems that the semantic is the reason, idk.
See the example, I've tried using some versions of dimensions, jquery, Jörn accordion's and JQ UI accordion and i cant managed it well =\
