Error when requesting AJAX in Elastic Beanstalk - CORS

I have a site in ASP.NET MVC on Amazon (it follows Link ), and it has the following JsonResult:

public JsonResult getPessoas(){

    List<Pessoa> pessoas = new List<Pessoa>();

    for(int i = 0; i++; i < 10)
    {
        Pessoa pessoa = new Pessoa()
        pessoa.ID = i;
        pessoa.Nome = "Nome " + i;
        pessoas.add(pessoa);

    }


    return Json(pessoas, JsonRequestBehavior.AllowGet)

}

That returns me the JSON, just access the link that you will see.

However, when I try in another application via AJAX to access this JSON, the following error appears to me:

  

Cross-Origin Request Blocked: The Same Origin Policy disallows reading   the remote resource at    link .   (Reason: CORS request did not succeed.) [Learn More]

I have read in some forums that I need to release CORS on the server, but how is it in an Elastic Beanstalk from Amazon Web Services, how can I do this?
