Reproduction of the problem

1. Open the project
2. Push the submit button twice

Current behavior

On the first time form submit the Check model value is correct - true. The value of the input does not get updated and on the second time - the Check model field returns false.

Expected/desired behavior

When the checkbox is checked the returned value should be always true. Analogically, when checkbox is not checked - false.
