Is it possible to return schema and UI schema updated from onChange?

Hi @TannicArturo98,

the `schema` and `uischema` do not change during the lifetime of the form. Therefore there is no need to hand them out via `onChange`.

If you don’t hand over the schema and ui schema to the form and let them autogenerate, then you can do this also manually. For this there is

```auto
import { Generate } from `@jsonforms/core`.

const schema = Generate.schema(data);
const uischema = Generate.uiSchema(schema);

```
