vuforia 9.1.7 'ITrackableEventHandler' could not be found

I have downloaded vuforia 9.17 and using it in unity. Have written a C# script, part of which is :

using Vuforia;

public class ABCD : MonoBehaviour, ITrackableEventHandler

And it throws an error on compiling : "ITrackableEventHandler' could not be found. Need help !!

 

Hi,

Please try DefaultTrackableEventHandler.

Thank you.

Hi,

I've replaced Monobehavior,ITrackableEventHandler with DefaultTrackableEventHandler and it's still not working also it gives me an error in the 

mTrackableBehaviour.RegisterTrackableEventHandler(this) line.

Hello

Same error here.

I should call 2 methods into MyItemClass. 

onTargetFound I should call MyItemClass.playMe()
