Change Handler
The change handler is triggered for an update made in any form field containing the boolean trigger_on_change as true. The change handler can be used to either add, remove or update fields in the form depending on the input made for a certain field.

| Attribute name | Description |
| operator | Details of the operator who is accessing the widget |
| environment | Details of the environment in which SalesIQ has been accessed |
| form | Details of the form object and the input values. |
