Displaying Age to datatables laravel - laravel

Question

i Have a function to showing Age on Model
This Model like this :
public function getAgeAttribute()
{
return Carbon::parse($this->attributes['tanggal_lahir'])->age;
}
and i parsing data on view ( without datatable) like
$users->age
but on datatable , not showing this data , just only Age is not showing
My Controller
public function indexDataTables_nonpns()
{
$users = User::with('master_agama','master_unit_kerja')->whereNotIn('nama',['admin'])->whereNotIn('roles_id',['2'])->get();
return Datatables::of($users)->addIndexColumn()
->addColumn('Nama', function ($users) {
return ''.$users->nama.'';
})
->rawColumns(['Nama' => 'Nama'])
->make(true);
}
My View
#push('scripts')
<script>
$(function() {
$('#table').DataTable({
processing: true,
serverSide: true,
responsive: true,
ajax: '{!! route('d_non_pns') !!}',
columns: [
{ data: 'DT_RowIndex', name: 'DT_RowIndex', orderable: false,searchable: false},
