OnScroll doesn't work in 5.6

Am I crazy? What is wrong with this code? It is attached to my main camera.

using System.Collections;
using UnityEngine;
using UnityEngine.EventSystems;

public class NewBehaviourScript : MonoBehaviour, IScrollHandler
{
public void OnScroll(PointerEventData data)
{
Debug.Log (“test”);
}
}

Never mind. I needed a physics raycaster on the main camera.
