AspNet Web Api 2 with owin token auth, not working with ionic app

I developed a asp.net web api 2 that worked the right way, today I decided to add token based authentication based on Taiseer Joudeh blog post http://goo.gl/dIJwzw. I am sure that is working because I can validate users, an generate tokens, using postman. And I have make the same requests in the token auth web api and the no auth web api, giving me exactly the same response.

But, when I try to use the web api with token auth with my ionic app, it makes the request, and I am getting the response from the web api in the console log, but it does not show anything int the view, of the info that I can see in the console.

Using the same ionic app code with the web api with no auth, it works perfectly, I do not what else todo, any help will be apreciated,

I am working with ionic v1.0.1 and AngularJS v1.3.13

thanks Alberto.
