Collecting text submitted in input field with ember-rails

I am following an ember-rails tutorial. It's using coffeescript and I'm writing in javascript. Essentially I have a form that when I submit text on it it should place the text below.

My controller looks like this:

Emberapp.ApplicationController = Ember.Controller.extend({

  entries: [],
  actions: {
    addEntry: function(){
      this.entries.pushObject name: this.get('newEntryName');
      this.set('newEntryName', "");
    }
  }
});

My template looks like this

<div id = "container">
  <h1>Emberails</h1>

  

  <ul>
    
      <li></li>
    
  </ul>

</div>

When I reload the page I get an error stating that 'name: this.get('newEntryName');' is an Unexpected identifier. I've been checking for the syntax rules online but I'm not sure if it is a coffeescript to javascript error or something else.
