Base on post MVC controller : get JSON object from HTTP body? You action should be:

[HttpPost]
public ActionResult DATACRUD()
{
    Stream req = Request.InputStream;
    req.Seek(0, System.IO.SeekOrigin.Begin);
    string json = new StreamReader(req).ReadToEnd();
    return Json(new { fromMVC = json });
}
