Change scene via new UI Buttons

Hi, I have problem with changing scene via new UI Buttons. I don’t know how can I do it. In old system I’m using

if (GUI.Button (new Rect (Screen.width / 2 - 30, 350, 60, 30), "Button") )
		{
			Application.LoadLevel(0);
		}

But how in new system UI?

Check out this tutorial from unity learn on how to use UI Button from new GUI.

I found answer here: http://forum.brackeys.com/thread/how-to-make-buttons-work-in-unity-4-6/
Thanks.
