### Bug report

When the TaskBoard is configured with the Kendo Form configuration for Card editing, the built-in Validator options don't run.

### Reproduction of the problem

1. Create a TaskBoard and add the Kendo Form as an editable configuration option.

2. Configure the built-in Validator options.

3. Specify the validation rules for the fields.

4. The fields are not validated when the task is edited.

A Dojo sample for reproduction: https://dojo.telerik.com/iSamumEw/4

### Expected/desired behavior

The task should be validated by using the built-in Validator options of the Kendo Form.

### Environment

* **Kendo UI version: 2021.2.616
* **jQuery version: 1.12.4
* **Browser: [all]
