it will be easier here than in the comments, but your issue is just linked to an escaping problem
you can see your directive here, working : http://jsfiddle.net/DotDotDot/S2KhB/1/
the issue :
data-ng-repeat="d in model.dossier | filter:{status:"POI"}"
ou can see that you used " everywhere which was understood by you browser as
data-ng-repeat="d in model.dossier | filter:{status:" +another attribute ignored
so you had an error, the only thing I did was using escaped '
data-ng-repeat="d in data | filter:{status:\'POI\'}"
and it seems to work =)
Have fun
