Make Image clickable

Unity Engine
1

So. Im creating GUI Image like this:

        GameObject obj = new GameObject("Image");
        obj.transform.SetParent(GameObject.Find("Canvas").transform);
        obj.AddComponent<Image>();
        obj.AddComponent<Interactable>();

Here is Interactable code:

public class Interactable : MonoBehaviour {
    void OnMouseUpAsButton() { Debug.Log ("click!"); }
}

And when im clicking on the image nothing happends. With other objects its do the trick, but not when Image in it. How can i do this?

P.S. Adding BoxCollider2D to the object doesn’t help.
