Making Loopback API Ember.js compatible

I'm trying out Loopback for an API that will talk to Ember.

Ember requires JSON to be contained in 'keys', e.g. for an account:

{ account:
   { domain: 'domain.com',
     subdomain: 'test',
     title: 'test.domain.com',
     id: 1 
} }

I've found some advice on the Google group about how to alter the response so that Ember will receive it, using afterRemote hooks.

E.g. in my models/account.js:

module.exports = function(Account) {

    Account.afterRemote('**', function (ctx, account, next) {
      if(ctx.result) {
        if(Array.isArray(ctx.result)) {
          ctx.res.body = { 'accounts': account };
        } else {
          ctx.res.body = { 'account': account };
        }
      }

      console.log(ctx.res.body);

      next();
    });

};

I see that the response is as it should be in the console .. however the JSON output at localhost:3000/api/accounts does not show the altered JSON object.

What is the correct way to alter the JSON response / requests in Loopback?

Ideally in a general way so it can be applied to all Models.
