hi,
Thank you for posting your questions here.
This is a know issue. We have fixed this in a new version and right now, the new version is in testing. We should be able to release it very soon.
For the trigger event on textbox text change, we don't expose any event out for users because we are trying to make it easy and simple to use. But in future version, we may expose some event out to let users to customize their needs.
Right now, the event handler we have are here:

Thanks.
