Backbone.js: "fetchmodel.fetch([options])
Resets the model's state from the server. Useful if the model has never been populated with data, or if you'd like to ensure that you have the latest server state. A "change" event will be triggered if the server's state differs from the current attributes. Accepts success and error callbacks in the options hash, which are passed (model, response) as arguments.
// Poll every 10 seconds to keep the channel model up-to-date.
setInterval(function() {
channel.fetch();
}, 10000);
