## FAQ

### Why `value` can exceed `min` or `max` in control?

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.
