Always do the event error $.ajax

I have a function for sending email. This function works normally, but it always triggers the error function, any error did not occur (I'm receiving email).

Follow my Javascript:

//Send mail
$("div.contato-pedidooracao form").submit(function () {

    var dataString = $(this).serialize();
    $.ajax({
        type: "POST",
        url: "Contato/SendMail",
        data: dataString,
        dataType : "json",
        success: function (data) { alert("OK"); },
        error: function (data) { alert("Error"); }

    });
});

Controller

[HttpPost]
public ActionResult SendMail(string name, string phone, string cel, string email, string message)
{
    try
    {
        using (var mail = new MailMessage())
        {

            mail.To.Add("--mailhere--");

            mail.From = new MailAddress("\"" + name + "\" <" + email + ">" );
            mail.Su开发者_开发百科bject = "Pedido de Oração - " + name;
            mail.Body = message;
            mail.IsBodyHtml = false;

            new SmtpClient().Send(mail);
        }
        return Json(new{Sucess = true, Message = "Email enviado com sucess!" } );

    }
    catch (Exception ex)
    {
        return Json(new{Sucess = false, Message = ex.Message } );
    }

}

I believe you need to add event.preventDefault to stop the submit event from bubbling up and really submitting the form to the server.

$("div.contato-pedidooracao form").submit(function (event) {
   event.preventDefault();
   ..... 
   .....
 });

Did you try just adding return false to the submit function:

$("div.contato-pedidooracao form").submit(function () {

  var dataString = $(this).serialize();
    $.ajax({
       type: "POST",
       url: "Contato/SendMail",
       data: dataString,
       dataType : "json",
       success: function (data) { alert("OK"); },
       error: function (data) { alert("Error"); }
   });
return false;  //right here
});
