Values not being set after settting checkboxes to 'checked' programatically/

### bug report

### What is the current behavior?

I have a table with main checkbox on the header and other checkboxes on the table. When I click the header checkbox all other checkboxes are being checked, but on validate returns only the main checkbox value and it does not catch the other checkboxes values.

### What is the expected behavior?

When I click the main checkbox, I want all of the values from the other checkboxes to be set, so I could validate them.

### What's your environment?

🏁 React Final Form version: 4.0.2

### Other information

When I click the other checkboxes individually it works fine, it only breaks when I click the main checkbox.
