Uncaught TypeError: Object [object Object] has no method 'fnStandingRedraw'-Collection of common programming errors

I have a datatable with few rows, I want to add new row in table :

  var oTable = $('#StudentsTable').dataTable();
  Table2.fnStandingRedraw();

when I init the dataTable I add :

            "bProcessing": true,
            "bServerSide": true,
            "bDestroy": true,
            "fnFilter": true,
            'bLengthChange': true,
            'bPaginate': true,
            'bStandingRedraw': true,

after ajax submit I want to redrow the table:

submitHandler: function(form) {
            var $modal = $('#ajax-modal');
            $modal.modal('loading');
            $(form).ajaxSubmit({
                dataType: 'json',
                success: function(result) {
                    if (result.Success) {
                        if (result.Data.Action == "add") {
                            var oTable2 = $('#StudentsTable').dataTable();
/*=>here is Call redraw */  oTable2.fnStandingRedraw();
                        }

here it give me error: Uncaught TypeError: Object [object Object] has no method ‘fnStandingRedraw’

some suggestions?
