callback handler never handle calendar

[ghost]

Hello!
I'm try to use calendar in my project. So, I can show calendar in bot.
But when pressing on calendar keys in Telegram then function never handle it. simple_cal_callback.filter() has no effects too.
My code:

@disp.callback_query_handler(dialog_cal_callback.filter())
async def process_get_check_in_date_state(query: CallbackQuery, data: dict) -> None:
    selected, date = await SimpleCalendar().process_selection(query, data)
    if selected:
        await query.message.answer(
            f'You selected {date.strftime("%d/%m/%Y")}'
        )

Upd: If I stop script and run again then function start handling. WTF?

it seems this is something related to callback handler and filters, did you tried in aiogram 3?
