Hello Wang,

I tried to reproduce the issue by using following demo for cascading ComboBox with templates for each ComboBox added and subscription for Select and Change events, but the events are triggered only once.

Could you please send us a runnable project where the issue can be reproduced, so we could have a look locally and provide further assistance.

Regards,
