Ember #each helper not working

So it seems Ember creates a controller (as I didn't specify one) and sets the model property defined in the route as a controller property. How come some of the other ways to loop through data don't work as shown below (simply don't output the returned data)? Is this the only way to loop through the returned data or am I missing something when solely using ember-cli-htmlbars (seems doesn't support handelbars anymore)? Previous apps had ember-cli-html bars and handlebars as dependencies and could use different aliases to loop through the data. Sorry, but I couldn't find much documentation on this.

//this works

<ul class="list-unstyled">
  {{#each post in model}}
  <li>
    {{post.title}}
  </li>
  {{/each}}
</ul>

//block params doesn't work

<h2>Posts</h2>

<ul class="list-unstyled">
  {{ log posts }}
  {{#each posts as |post|}}
  <li>
    {{post.title}}
  </li>
  {{/each}}
</ul>

//neither does this

<ul class="list-unstyled">
  {{#each}}
  <li>
    {{title}}
  </li>
  {{/each}}
</ul>

//http-mock for api endpoint

res.send({
  'posts': [
    {
      id: 1,
      title: "Bananas"
    },
    {
      id: 2,
      title: 'Apples'
    }
  ]
});

//routes/posts.js

import Ember from 'ember';

export default Ember.Route.extend({
  model: function() {
    return this.store.find('post');
  }
});
