Accessing the Cast API from within an extension page

I was working on a chromecast app, and I wanted to incorporate it into a chrome extension. I'm also using knockout.js in order to help with some of the UI. I have two pages, one is unsandboxed (http://jsfiddle.net/AuJaX/3/), and the other is sandboxed (http://jsfiddle.net/V2dJc/1/). None of the console.log's ever get called. My manifest is below:

{
  "manifest_version": 2,
  "name": "__MSG_app_title__",
  "description": "__MSG_app_description__",
  "version": "0.1",
  "content_scripts": [
    {
  "matches": ["<all_urls>"],
      "js": ["js/content/content.js"]
    }
  ],
  "background": {
    "scripts": ["js/back/background.js"],
    "persistent": false
  },
  "permissions": [
    "tabs",
    "contextMenus"
  ],
  "page_action": {
    "default_title": "__MSG_app_title__",
    "default_icon": {
      "19": "images/icon-19.png"
    }
  },
  "sandbox": {
    "pages": ["sandboxed.html"]
  },
  "icons": { "48": "images/icon.png" },
  "default_locale": "en"
}

Is there anything that I'm doing wrong, or is this something that's not supported (yet??)?

Did you whitelist the domain you are trying to use the extension on? Currently to have the Cast API injected into the page you need two things:

<html data-cast-api-enabled="true">

and you need to follow the steps at the bottom of this page (whitelisting in the extension, not the same as the Google Cast device whitelisting):

https://developers.google.com/cast/whitelisting#whitelist-chrome

That said, I doubt this is going to work. The instructions are for getting the Cast API injected into a regular web page. However, if I'm not mistaken you want the API injected into your Chrome extension page. I don't know if it will be made available there, since I don't think two different extensions are allowed to interact.
