I'm trying to refresh the view after a wizard is closed, in odoo 9,  without reload all the page, like this

return {
    'type': 'ir.actions.client',
    'tag': 'reload',
}

So following the post https://www.odoo.com/es_ES/forum/ayuda-1/question/how-to-refresh-the-original-view-after-wizard-actions-10268 I append to the python function:

return {'type': 'ir.actions.act_close_wizard_and_refresh_view'} #TODO check this so not reload all the view

And a javascript file with the extend of the action_manager

odoo.define('sale_order_variant_mgmt.action_manager', function(require) {
  var action_manager = require('web.ActionManager');
  var MyModuleActionManager = action_manager.include({
    ir_actions_act_close_wizard_and_reload_view: function (action, options) {
      if (!this.dialog) {
        options.on_close();
      }
      this.dialog_stop();
      this.inner_widget.active_view.controller.do_reload();
      return $.when();
    },
  });
  return MyModuleActionManager;
});

But I'm getting the following error 
Action manager can't handle action of type ir.actions.act_close_wizard_and_refresh_view
