$ .getJSON does not return a response with MVC3

I spent a lot of time studying this and just don’t see what happened. I have the following:

$.getJSON(
                '/adminStatus/GetJsonData',
                { name: $('#textSearch')[0].value },
                function (data) {
                    alert("3");
//                  $('#studentList > div').remove();
//                  for (s in data) {
//                      alert("4");
//                      var student = data[s];
//                      $('#studentList').append('<div>(' + student.StudentId + ') ' + student.FirstName + ' ' + student.LastName + '</div>');
//                  }
                }
            );

This code runs an action in my controller, and this action returns data. This is actually code from another example:

public JsonResult GetJsonData(string name)
        {
            return new JsonResult
            {
                Data = (from student in Student.GetStudentDataList()
                        where student.LastName.StartsWith(name)
                        select student).ToArray<Student>()
            };
        }

I check and the data is populated with data.

However, nothing happens with the returned data, and when I added comments, I can not even get a warning ("3").

Am I doing something really clearly wrong? I think I am copying a working example, but nothing is returned, and the function (data) {} does not seem to be executed.

Any help would be greatly appreciated.

Thank,
