how to useyajrabox setTransformer and search

Can't use yajrabox setTransformer for search data

in controller-------------

return [ 'user_id' => (int) $item->user_id, 'name' => (string) $item->userDetails['first_name'].' '.$item->userDetails['last_name'], 'username' => (string) $item->username, 'email' => (string) $item->email, 'phone' => (string) $item->userDetails['phone'], 'register_date' => (string) Carbon\Carbon::parse($item->register_date)->format('H:i:s d-m-Y'), 'banned' => $status, 'action' => $action, ]; })

And in blade-------------

$(document).ready( function () {

    $('#user_datatable').DataTable({
        processing: true,
        serverSide: true,
        ajax: {
         url: "",
         type: 'GET',
         data: function (d) {
         }
        },
        columns: [
                 { data: 'user_id' },
                 { data: 'name', orderable: false},
                 { data: 'username'},
                 { data: 'email' },
                 { data: 'phone',orderable: false,searchable: false},
                 { data: 'register_date' },
                 { data: 'banned'},
                 { data: 'action',orderable: false,searchable: false}
              ]
     });
});
