Emberjs managing multi-language contents

I'm making a dashboard of an application using emberjs, and I've got a content that should be localized, I don't know If I'm stupid and I don't see how can I localize, or If there is nothing on internet about that. I only found this link http://ift.tt/1b63bQT talking about that.

My usually aproach when I'm using mobile devices, was to use a json data like the following:

{"template":{
    "name":{ 
         "es":"Prueba multi-idioma 1"
         "en":"Multi language test 1"
     },
     ...
 }

In the case you only need one language, you can request to the server with a header or a get parameter using that.

In the link I found, I understand the second approach was something like:

{"template":{
    "name":[ 
         {"lang":"es", "content":"Prueba multi-idioma 1"}
         {"lang":"en", "content":"Multi language test 1"}
     },
     ...
 }

This means that to found a language, you should made a search (I know is not difficult on emberjs), but If I understand correctly, It means every language entry for the content, is an ember object, and if I'm not wrong, ember require an ID for every object you create, and the {"lang":"es", "content":"somecontent"} it's an object.

Thanks everyone, and sorry If this is a stupid question.
