[AJAX] Cakephp Ajax pagination search and refresh

Bonjour,
J'ai un petit soucis avec un script Ajax qui sert à filtrer des projets à l'aide de différents champs, pour le moment juste un select avec dedans une liste de statuts et je dois récupérer les éléments qui ont uniquement ce statut, j'arrive à récupérer les données filtrées mais au moment de les re-passer à ma vue, euh PAAN ! :cry: vous pouvez voir le site web à cette url : http://bb-on-air.com/website/projects, PS : J'ai laissé un debug et mis des console.log() ça peut aider

j'utilise cakephp
j'ai donc des Modèles Vues et Controllers

Mon Modèle : Model/Project.php
