Uncaught TypeError: Cannot call method 'push' of undefined
<p>I am getting this error on the console in Chrome as soon as the page loads. I really don't get what's wrong cause I've tested the PHP side and there doesn't seem to be anything wrong with it. It was working before as well but now I don't know what's changed cause all I've done is changed my Models and it works for everything but this. I would try to be more specific by pointing where the error might be but I haven't the slightest idea cause it's not telling me!</p>

<p>I've pasted it into JS Fiddle.
