Ember.js template rendering - ember.js

Question

I'm possibly reading the docs wrong. Can someone please check out my gist and tell me why the invoices/index template is not rendering?
When I read the ember.js docs it states it should render
posts
↳posts/index
(invoices/index in my case). The invoices template renders however.
Handlebars:
<script type="text/x-handlebars" data-template-name="application">
<h1>Ember Committers</h1>
<nav>
{{#linkTo "index"}}Index{{/linkTo}}
{{#linkTo "about"}}About{{/linkTo}}
{{#linkTo "invoices"}}Invoices{{/linkTo}}
</nav>
{{ outlet }}
</script>
<script type="text/x-handlebars" data-template-name="invoices">
<h1>Invoices</h1>
</script>
<script type="text/x-handlebars" data-template-name="invoices/index">
<ul>
{{#each invoice in invoices }}
<li>{{#linkTo "show" invoice.id}}{{ invoice.id }}{{/linkTo }}</li>
{{/each }}
</ul>
</script>
<script type="text/x-handlebars" data-template-name="invoices/show">
<p>Invoice - {{ name }}</p>
</script>
<script type="text/x-handlebars" data-template-name="phone">
<p>Contributor - {{ title }}</p>
</script>
<script type="text/x-handlebars" data-template-name="about">
<p>About {{ title }}</p>
</script>
<script type="text/x-handlebars" data-template-name="index">
<p>Index</p>
</script>
JavaScript:
<script type="text/javascript" defer>
var App = Ember.Application.create({
LOG_TRANSITIONS: true
});
App.ApplicationView = Ember.View.extend({
templateName: 'application'
});
App.Router.map(function () {
this.route("about");
this.resource("invoices", { path: "/invoices" }, function () {
this.resource("show", { path: "/:id" });
});
});
var invoices = [
{id: 1},
{id: 2}
];
App.AboutRoute = Ember.Route.extend({
setupController: function (controller) {
// Set the IndexController's `title`
controller.set('title', "My App");
}
});
App.InvoicesIndexController = Ember.ArrayController.extend({
invoices: invoices
});
</script>

You need to include an {{outlet}} tag in your invoices template. Since index and show are nested resources of invoices, their templates get rendered inside the outlet that you specify in the invoices template.
Take a look at the nested resources part of the Ember.js guide.
