Developer handle data by their own in control. It will make data out of sync if InputNumber change display value. It also cause potential data issues when use in form. ### Why dynamic change `min` or `max` which makes `value` out of range will not trigger `change`? `change` is user trigger event. Auto trigger will makes form lib can not detect data modify source.
