尝试调用控制器时jQuery一直失败

I am trying to call a controller action in ASP.Net MVC 5 from a jQuery ajax method. Everything seems to be in place and correct, however my ajax keeps failing. The error return keeps presenting itself and my page does not refresh. However, my controller does get hit. If I set a break point in the C# code under the specific action I am trying to access all goes according to plan. I am trying to call a controller action in ASP.
