jquery commands not working in tests using hbs rendering in ember.js

I've been working on writing my own component tests in Ember.js 2.5. I'm currently trying to test a property change on button press. The tests can run just fine and throw no errors, but the jquery commands within the test don't seem to work. e.g this.$('button').click();

I've followed the guide here, http://ift.tt/1Titqon, and even followed along doing exactly what they did same component names and everything, but still nothing jquery works or throws an error.
