未使用不同类型触发更改时

我重写了onchange\u partner\u id,如果我创建了类型为“contact”的联系人,它会非常有效,但是如果我选择了类型“delivery address”,onchange不会被触发。。为什么会这样?我该怎么解决?

def onchange_parent_id(self, cr, uid, ids, parent_id, context=None):
        res = super(ResPartner, self).onchange_parent_id(cr, uid, ids, parent_id, context=context)
        new_contact_obj = self.browse(cr,uid,ids,context=context)
        parent_obj = self.browse(cr,uid, parent_id,context=context)
        if not new_contact_obj.multiply_pricelists_ids:
            new_contact_obj.multiply_pricelists_ids = parent_obj.multiply_pricelists_ids
        return res
