replace action for sails.js controller

/**
 * <NameOfYourModel>Controller
 *
 * @module      :: Controller
 * @description :: A set of functions called `actions`.
 *
 *                 Actions contain code telling Sails how to respond to a certain type of request.
 *                 (i.e. do stuff, then send some JSON, show an HTML page, or redirect to another URL)
 *
 *                 You can configure the blueprint URLs which trigger these actions (`config/controllers.js`)
 *                 and/or override them with custom routes (`config/routes.js`)
 *
 *                 NOTE: The code you write here supports both HTTP and Socket.io automatically.
 *
