How to write a callback function for DateTimePicker?

[asphub]

I tried the subscribe method with event namespace as "change" but it not working.

datetimepicker.subscribe('change', (e) => {
  console.log('Changed');
});

Look at the linked picker example.

linkedPicker1Element.addEventListener(Namespace.events.change, (e) => {
  linked2.updateOptions({
    restrictions: {
      minDate: e.detail.date,
    },
  });
});
