You need to set some things up in jsFiddle for this to work.
First, on the left panel, under “Frameworks & Extensions”, select “No wrap – in <body>”.
Now, under “Fiddle Options”, change “Body tag” to <body ng-app='myApp'>
In the JS panel, initiate your module:
var app = angular.module('myApp', []);
