How to make Listner with Select

[nabiullin]

Hello. I have Listner class with Layout

 protected function layouts(): iterable
    {
        return [
            Layout::rows([
                Relation::make('client_id_s')
                    ->fromModel(Client::class, 'name')
                    ->title('Клиент')
                    ->placeholder('Выберите клиента')
                    ->help('Поиск по номеру')
                    ->searchColumns('name', 'phone'),

                Select::make('children_s.')
                   // ->empty('No select', 0)
                   // ->options($this->values)
                   // ->fromModel(Child::class, 'name')

            ])
        ];
    }

I want to update Select variant by change value in client_id_s
So I have added target

    protected $targets = [
        'client_id_s'
    ];

And make handle

public function handle(Repository $repository, Request $request): Repository
  {
      
      $client =  Client::findOrFail($request->input('client_id_s'));
      $children =$client->children()->get();
      $childrenOptions = [];
      $childrenOptions2 = [];

      foreach ($children as $child) {
          $childrenOptions[$child->id] = $child->name;
          $childrenOptions2 = $child->name;
      }
      $values = $childrenOptions;
      return $repository
          ->set('children_s.', $childrenOptions)
          ->set('client_id_s', $client->id);

  }

But values doesn't update. No errors in output, only empty in Select::make('children_s.')
