How to make a GameObject a button?

I’m developing a game in which you have to find a button in a room, for the script i’m using this and just putting it on the button

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class OnClickLoadNextLevel : MonoBehaviour {
	void OnMouseUpAsButton() {
		SceneManager.LoadScene (SceneManager.GetActiveScene().buildIndex + 1);
	}
}

but this creates some weird bug where you can’t be too close to the button to click it, and it sometimes takes a few clicks to find the point at which it works, is there any other way i could do this?
If you wan’t to see the bug yourself go to

Use OnMouseDown() method of monobehaviour

It will be called when you click gameobject

Write your code in this method

reference : OnMouseDown

in ufps demo, there is a button implementation.
i think they are using raycast.
