displaying nested json data using each in Emberjs

I have successfully displayed JSON objects unto my template thanks the answer on my previous stackoverflow post setting data from route to controller error in Emberjs

Now, I am trying to display a nested JSON data objects to my template using the {{#each}} helper.

here is my code: http://ift.tt/1LwzVxi

It doesn't give me any errors on my dev console and also it just gives me blank text. I've also wrote the code in different ways but still no luck..

any feedback would be appreciated

thanks,
