and when method not found, than it will gone to error or any function not called by ajax call.
$.ajax({

data: formData,
url: "/Forms/GetJobData",
dataType: 'json',
contentType: false,
processData: false,
success: function (response) {
if (response.success) {
alert(response.responseText);
} else {
// DoSomethingElse()
