For Draging stuff I just do this :

using UnityEngine;
using UnityEngine.UI;
using UnityEngine.EventSystems;

public class Draggable : MonoBehaviour, IBeginDragHandler, IDragHandler, IEndDragHandler {



    public void OnBeginDrag(PointerEventData eventData) {

    }

    public void OnDrag(PointerEventData eventData) {
        //Debug.Log ("OnDrag");

        this.transform.position = eventData.position;

        }

    public void OnEndDrag(PointerEventData eventData) {
        Debug.Log ("OnEndDrag");

    }
}
