**Plunkr Case (Bug Reports)**
https://stackblitz.com/edit/primeng-radiobutton-demo-xj3pfd?file=src/app/app.component.html

**Current behavior**
Using PrimeNG 10.0.0 and model driven forms the radiobutton component is not un-checking the radiobutton when another radiobutton gets checked. The value in the form gets changed correctly.

**Expected behavior**
Only the currently checked radiobutton should be rendered as checked.

**Minimal reproduction of the problem with instructions**
A simple example is found in the stackblitz above. 

A simple formgroup with only one property is created at init. Then there's 2 radiobuttons to change the testvalue. Checking the first radio works fine. Checking the other radio also sets the correct value, but the first radio is still checked.

Using ngModel works fine.
