How to move focus of Toggle's Navigation?

Unity Engine
1 
public void EquipInvenChanged(Toggle tog)
    {           
        if (tog.isOn)
        { EventSystem.current.SetSelectedGameObject(tog.gameObject);
         }
     }

But I call above function by click some toggle, keyboard’s direction key does not react.

Why and how to make it work?

I already set many toggle’s navigation as explicit and set reference each others.
