Why boolean = false?

Question

Unity

public bool IsFree = true;

public void CreateOS()
    {
        Debug.Log(IsFree);
    }

But when clicking on the button (CreateOS method) outputs False, not True

Answer 1

public void CreateOS(bool ToggleStatus){ 
        Debug.Log(ToggleStatus);
}

And in OnValueChanged point to the CreateOS() method
