WebYou can use a rate limiting observable to avoid too many events which is especially useful if the fields are text inputs. Add extend ( { rateLimit: 500 }) before the subscribe function for that case. I believe rateLimit: 0 or extend ( { deferred: true }); may be useful if you find you are getting multiple events raised for each change.
