I cant get {{render}} helper to link a model with a template ¿Why?

I have share a very basic example of what I understand is how to use the {{render}} helper, but I can not get the data from the model to be render. I dont really understand why this happens, since I am following the example given in the emberjs guide.

The second parameter of the {{render}} is theorically responsible for linking the given model to the template (first parameter), so I guess it means you dont have to call it from the controller.

I need the {{render}} helper beacuse I dont want the model to be asociated with the route, but just link it explicetely with the template.

If you could tell me what I am doing wrong, I would really apreciate it. Thanks in advance
