Failed to loop through nested JSON array (uppercase properties) using Handlebars JS with Ember JS

I am learning Ember JS and Handlebars JS, so I am very new to this.

I am having a problem with a loop of nested JSON arrays. I can not scroll the "Pages" in JSON below.

Here is the JSON:

{
    "Pages": [
      {
        "Id": 1,
        "Name": "Page 1",
        "Objects": [
          {
            "Width": 100,
            "Height": 200,
            "Type": "Shape"
          },
          {
            "Width": 150,
            "Height": 250,
            "Type": "Image"     
          }
        ]
      },
      {
        "Id": 2,
        "Name": "Page 2",
        "Objects": [

        ]
      }
    ],
    "Settings": {
        "URL": "http://THEURL",
        "Location": true,
        "Navigation": true
     },
     "Id": 1,
     "Title": "The Title",
     "Description": "The Description"
}

This is my handlebars template:

<script type="text/x-handlebars" id="pages">
<div class="container">
    <div class="row">
        <h1>{{Title}}</h1> <!-- This works -->
        <h2>{{Description}}</h2> <!-- This works -->

        <!-- This doesn't work: -->
        <ul>
        {{#each Pages}}
              <li>Page ID: {{Id}} <br /> Page Name: {{Name}} <br />
                  <ul>
                  {{#each Objects}}
                    <li>{{Type}}</li>
                  {{/each}}
                  </ul>
              </li>
        {{/each}}
        </ul>

    </div>
</div>
</script>

Also, when I just add:

{{Pages}}

in the descriptor template, the output in the browser:

[object Object],[object Object]

I am not sure if this is a problem or not.

Portable variables are considered a global area, you need to fully qualify them or make them lowercase.

<div class="container">
    <div class="row">
        <h1>{{model.Title}}</h1> <!-- This works -->
        <h2>{{model.Description}}</h2> <!-- This works -->

        <!-- This doesn't work: -->
        <ul>
        {{#each page in model.Pages}}
              <li>Page ID: {{page.Id}} <br /> Page Name: {{page.Name}} <br />
                  <ul>
                  {{#each obj in page.Objects}}
                    <li>{{obj.Type}}</li>
                  {{/each}}
                  </ul>
              </li>
        {{/each}}
        </ul>

    </div>
</div>
