In the view, you have this :
<kanban default_group_by="stage_id">
You need to specify how sort the group in your class.
def _read_group_state(self, cr, uid, ids, domain, read_group_order=None, access_rights_uid=None, context=None):
pass
_group_by_full = { 'stage_id': _read_group_stage_ids}

Please Mathieu Benoit! can you show us how _read_group_state function should look like?

here is the his mine:

def _read_group_state(self, cr, uid, ids, domain, read_group_order=None, access_rights_uid=None, context=None):
print '_read_group_state'
access_rights_uid = access_rights_uid or uid
renting_obj = self.pool.get('mymodule.renting')

renting_ids = renting_obj._search(cr, uid, domain, order=read_group_order, access_rights_uid=access_rights_uid, context=context)
result = renting_obj.name_g
