not able to send values from angularjs to controller

[sri Srinu]

--- calling this method on a button click 

$scope.Name=srinu

$scope.dyanmictab = function () {

            console.log($scope.director);

            $http({

                method: "POST",

                url: "http://localhost:64397/Api/student/GetStudentsdynamic",

                dataType: 'json',

                data: { name: $scope.Name },

                headers: { "Content-Type": "application/json" }

            });

-------------- in Controller 

   [Route("GetStudentsdynamic")]

        [HttpPost]

        public string GetStudentsdynamic([FromBody] string  name)

        {

             

            catch (Exception e)

            {

                name= null;

            }

            return name;

        }

getting name as null from controller side 

Please suggest me the correct code
