How to destroy the first datatable initialization (DataTable inside modal)

I have a modal that displays a table. And I use a datatable plugin so that the data is searchable and sortable. It works correctly at first, but when I close the modal and click another link to the same modal, it displays an error. I found a solution to destroy a DataTable, and I put destroy()datatable before initializing, but then no data is displayed inside the table. If I placed it after initialization, it gave me an initialization error the second time I clicked the button. How can i solve this?

here is my code:

    $.ajax({
      url: "<?php echo site_url('admin/group/getMember')?>",
      type: 'POST',
      data: { 'groupID': id},
      dataType: 'JSON',
      success: function(result){
        $('#records_table tbody').empty();
        // $('#records_table').DataTable({
            // "bLengthChange": false,
            // "paging":false,
        // });
        $('.modal-header #hdrmsg').text(result[0].fname);
        var trHTML='';

         $.each(result, function (i, item) {
            trHTML += '<tr><td>' + item.fname + '</td><td>' + item.mname + '</td><td>' + item.lname + '</td></tr>';
        });
        $('#records_table tbody').append(trHTML);
        $('#records_table').DataTable({
            "bLengthChange": false,
            "paging":false,
        });
        $('#records_table').DataTable().fnDestroy();

      }

  });
