Bootstrap collapse ne bascule qu'une fois

Je tire encore une fois mes cheveux ici ... Donc, j'ai donc un effondrement de bootstrap fonctionnant avec jsfiddle ( http://jsfiddle.net/rasreye/xtppth/1/ ) - Mais lorsque j'ajoute à mon site, il ne s'effondre qu'une seule fois ... (c.-à-d. cliquer sur une en-tête qu'il s'ouvre, cliquez à nouveau sur une option. Il ferme, cliquez à nouveau et rien)

Voici un lien vers la page réelle avec le problème: http: / /www.urbanoffering.com/custom-optimizations P>

Heres le JS P>
