First off you need to modify application/config/rest.php
```
$config['rest_default_format'] = 'json';
```
This will ensure that when your api call is made the server will return json without an additional segment.

You must then create an api controller that will return your codeigniter model in the correct format for Ember.js
```
<?php
require(APPPATH.'/libraries/REST_Controller.php');

<input type="checkbox" {{action "foo" on="change"}}>

App.MenusController = Ember.ObjectController.extend({
  // initial value
  isExpanded: false,

  actions: {
    foo: function() {
      alert('works');
    }

class Binarygeometry_Tallgallery_AjaxController extends Mage_Core_Controller_Front_Action
{
   public function indexAction ()
   {
   		//URL EXAMPLE  tallgallery/ajax/index?prodid=187&&imagid=551
   		$productId = $this->getRequest()->getParam('prodid');  // get product id from url
   		$imageId   = $this->getRequest()->getParam('imagid'); 	// get image id from url
   		$imageSize = $this->getRequest()->getParam('resize');

		Mage::helper('catalog/product')->initProduct($productId, $this);  // make available to layout

// this is the background code...

// listen for our browerAction to be clicked
chrome.browserAction.onClicked.addListener(function (tab) {
	// for the current tab, inject the "inject.js" file & execute it
	chrome.tabs.executeScript(tab.ib, {
		file: 'inject.js'
	});
});
