Sencha Touch 2 array parsing

Question

I'm new to sencha touch and I'm trying to parse an array of data (this doesn't seem like an uncommon use case but I can't find anything about it online). I followed the sencha ext.data.reader.json doc on nested json, but it doesn't work. Here are my models: Search Results (to hold multiple search results):

Ext.define('GS.model.SearchResults', {
extend: 'Ext.data.Model',
autoLoad: true,
config: {
    fields: [
        {name: 'query', type: 'string'},
    ],
    hasMany  : {model: 'SearchResult', name: 'results'},

        }
});

And search result, to hold an individual search result

Ext.define('GS.model.SearchResult', {
extend: 'Ext.data.Model',

config: {
    fields: [
        {name: 'id',     type: 'int'},
        {name: 'name',      type: 'string'}
    ],
    belongsTo: 'SearchResults'
}
});

Then in my controller, I have this code:

var store = Ext.create('Ext.data.Store', {
        autoLoad: "true",
        model: "GS.model.SearchResults",
        proxy: 
        {
            type: 'ajax',
            url : 'www.someurl.com/?query=somequery',
            reader: {
                type: 'json'
            }
        }
    });
    store.load({
        callback: function() {
            console.log("Done Loading");
            var root = store.first();

            console.log("Results for " + root.get('query')); //this prints correctly


            console.log(root.results());//THIS IS THE LINE IM INTERESTED IN
            console.log(root.raw.results);//this weirdly works
            //now I want to print each search results name
            root.results().each(function(result) {
                console.log("Song: " + result.get('name'));
            });

        }
    });

}

When I log root.results(), I get

Uncaught TypeError: Object [object Object] has no method 'results'

This is exactly how they do it in the docs, so does anyone know why this isnt working???

Edit: Here is the doc I was following

Are you sure you need a separate model definition just to contain more than one SearchResult? Why not just store your SearchResults in an array? — Daniel Miladinov
That makes sense to me but that isn't how they do their examples. I just added the link to the question btw — Jameo
Also I plan to drill further down into this heirarchy later, I'm just trying to get this simple example working — Jameo

The best way to check your error is to debug in chrome console. After callback you will find your records in root.raw or root.data.

I use to debug in chrome console and write the required code.
