Why doesn't ajax post call controller method in MVC?

Question

I have read almost every question on SO about Ajax Post to controllers. I have tried every single solution that I saw here. Nonetheless, my post still not working. Thus, please do not consider it as a duplicate, at least until I get an answer.

public class BlogController : Controller
    {
    [HttpPost]
    public ActionResult Test(BlogElement data)
    {
        return null;
    }

    public class BlogElement
    {
       public string HtmlContent { get; set; }
       public string Date { get; set; }
    }

And the Ajax part

var data_ = { HtmlContent: "someContent", Date: "someDate" }
    $.ajax({
        type: "POST",
        url: "/Blog/Test",
        dataType: "json",
        data:data_ 
    });

Ajax response error says "Not Found". Here is my route config. I am actually only using attribute routing.

routes.MapMvcAttributeRoutes();

What might be wrong with this configuration?

Define "not working". What's the status code of the response? — haim770

Apparently, calling MapMvcAttributeRoutes() in your RoutesConfig doesn't mean the default {controller}/{action} route will be registered as well.

Either add it:

routes.MapRoute(
   name: "Default",
   url: "{controller}/{action}/{id}",
   defaults: new { controller = "Home", action = "Index", Id = UrlParameter.Optional } );

Or decorate your action with the appropriate [Route] attribute:

[HttpPost]
[Route("Blog/Test")]
public ActionResult Test()
{
    // ...
}
