Retrieving values from json objects into my template (HTML) using ember

This is how i'm fetching a single JSON value inside my template .. My application route :

import Ember from 'ember';
export default Ember.Route.extend({
model(){
    return {    url:"myurl" };
},setupController(controller,model)
{
    controller.set("URL",model.url);
}
});

application.hbs :

<h1></h1>

This works fine. What I want to do now is to fetch the values from this kind of JSON object into my template :

{"employee":
 [{
"id":"1001",
"name":"Employee1",
"address":{
  "Street":"25 West Street",
  "city":"City1",
  "state":"State1",
  "Country":"US"
}
}    
]}

• What Code should I be using in my application route to set the controller?

• How do i retrieve the value of each and every key in my JSON object into my template?

• Is there a way to fetch not only the value of the JSON object, but also its key inside my template ? If so, how?
