Generate event by pressed button in Unity with the leapmotion

[tenpura_jizou]

Hi guys!
I'm student using leap motion with unity and beginner in developer. I am currently using some tools from the anchor behaviour scripts in the Leap Motion examples, and I try generating event with console.WriteLine by pressed button in Dynamic UI.

before

public Action OnPress = () => { };
public Action OnUnpress = () => { };

after

public Action OnPress = () => { Console.WriteLine("yes");};
public Action OnUnpress = () => { Console.WriteLine("no"); };

---

but,it is no action in console.....
please advise me

I understand it.
Console.WriteLine → Debug.Log
