How can i update field Information when reactive doesnt work

[trim vale]

Hello folks,
I would like to update the array for the disabledDates() as soon as the item changes. I tried using afterStateUpdated in the select field for Item, but unfortunately it doesn't work. Then I made the field reactive and wrote a small function that outputs the occupied days based on the item.
When editing, the correct days are loaded for the item (screenshot 1). But if I change the item or add a new one, no data is loaded? How can I make this reactive?

` Select::make('item_id')

->options(Item::query()->pluck('name', 'id'))
->required()
->reactive()
->columnSpan([
'md' => 5,
'lg' => 2,

$set('date_range', null);
self::updateTotals($get, $set);

Maybe an issue with DateRangePicker, because disabledDates in Filament Date Picker will work using native(false)

https://filamentphp.com/docs/3.x/forms/fields/date-time-picker#disabling-specific-dates

Forms\Components\Select::make('item_id')
    ->live()
    ->options([
        '1' => 'Option 1',
        '2' => 'Option 2',
        '3' => 'Option 3',
    ]),
Forms\Components\DatePicker::make('date')
    ->native(false)
    ->disabledDates(fn (Forms\Get $get): array => match ($get('item_id')) {
        default => [],
        '1' => ['2024-10-21'],
        '2' => ['2024-10-22'],
        '3' => ['2024-10-23'],
    }),

Thank you for your answer.
Is there another way to dynamically reload the data? So far I have only ever found a reference to a custom component, but there must be a way to load the data dynamically via a backend controller logic. Would you have an idea?

this works using DataPicker, actually. I think the issue is DateRangePicker..
