I'm trying to have a reload button on a custom tree view, here is the code on my .py:

@api.multi
def reload_page(self):
    model_obj = self.env['ir.model.data']
    data_id = model_obj._get_id('module_name', 'view_id')
    view_id = model_obj.browse(data_id).res_id
    return {
        'type': 'ir.actions.act_window',
        'name': _('String'),
        'res_model': 'rest.order',
        'view_type' : 'form',
        'view_mode' : 'tree',
        'view_id' : kitchen_orders_action, # Kitchen_orders_tree_view raise the same error #
        'target' : 'current',
        'nodestroy' : True,
    }

Caled on view by:

<button type="object" name="reload_page" string="Reload Page" />

And here is the error raised:

  File "/home/effe/odoo/addons/web/controllers/main.py", line 928, in _call_kw
    return getattr(request.registry.get(model), method)(request.cr, request.uid, *args, **kwargs)
AttributeError: 'rest.order' object has no attribute 'reload_page'
