Printing Ember.js model on Handlebars

I have the following ember.js code:

app.js:

Game = Ember.Application.create({
    ready: function() {
        Game.gameController.getChallenge();
        Game.gameController.participants.pushObject(Game.participants("player1","player1.jpg"));
    }   
});

Game.challenge = Ember.Object.extend({
    challengetype: null,
    description: null,
    id: null
});

Game.participants = Ember.Object.extend({
    name: null,
    image: null  
});

Game.gameController = Ember.ArrayController.create({
    content: [], 

    current: "",

    participants: [],

    getChallenge: function() {
        var self = this;
        var url = "http://api:9393/challenge";
        $.getJSON(url, function(data) {
            self.insertAt(0,Game.challenge.create(data.challenge));
            self.set('current', data.challenge.description);
        }); 
    },  
});

Game.NewChallengeView = Ember.View.extend({
    click: function(evt) {
        Game.gameController.getChallenge();
    }
});

and the template:

<div id="participants">
    {{#each Game.gameController.participants}}
        {{name}}  
    {{/each}}
</div>

current challenge:
<div class="tooltips-gray">
    {{Game.gameController.current}}
</div>

I have 2 questions:

Thanks.

I've converted your code to a working fiddle here: http://jsfiddle.net/KbN47/8/

The most natural way to bind to the first element of the array is using firstObject. As of Ember 0.9.5, firstObject and lastObject are not observable, due to performance impact. The Ember team hopes to fix this in the future.

If you don't plan to make many changes to the array in your app, the naive override of firstObject I provided in the fiddle should work for you.

Regarding your second question, I extracted the participants to separate controller for clarity and fixed a few issues with your code.
