Alternative solution with incoding framework:

Controller 

        [HttpGet]
    public ActionResult ValidatePin()
    {
        return IncJson(new AlertVM(){Message = "Some thing"});
    }

Razor page

@(Html
  .When(JqueryBind.Click)
  .Do()
  .AjaxGet(Url.Action("ValidatePin","Pin"))
  .OnSuccess(dsl => dsl.Utilities.Window.Alert(Selector.Incoding.Data<AlertVM>(r=>r.Message)))
  .AsHtmlAttributes()
  .ToButton("clickme"))

why do you insist not to implement an action method instead of this static method? my second question is what your method actully does? validation something? so how do you pass it to this method?

Think you might want something like this:

public JsonResult ValidatePin(string id) /*id=pin*/
{
    bool result;
    // do something
    return Json(new { IsValid = result, Message = "something" }, JsonRequestBehavior.AllowGet);
}


$.ajax({
                url: '/validatepin/' + pin,
                type: 'POST',
                dataType: 'json',
                data: json,
                contentType: 'application/json; charset=utf-8',
                success: function (data) {

        alert(data.message + '  ' + data.IsValid);
                }
            })
