How to detect double click on ui image?

Is there a simple way for detecting double click on images in the UI in Unity 5? Or can it be only done by counting time between clicks?

My question is for a project made for mobile devices.

Attach it to GameObject you want to handle double click :

using UnityEngine;
    using UnityEngine.UI;
    using System.Collections;
    using UnityEngine.EventSystems;
    public class DoubleClick : MonoBehaviour, IPointerDownHandler
    	public void OnPointerDown (PointerEventData eventData) 
    		if(eventData.clickCount == 2){
    			Debug.Log ("Double Click");
    			eventData.clickCount = 0;
