Virtual Buttons Calling OnButtonPressed( ); from Raycast

Hello, i want to call the OnButtonPressed Virtual Button method from A Raycast script, i got an error when i call the OnButtonPressed method due to wrong parameter.

I would like to know the best way to do it and solve my case, maybe i'am doing something wrong, anyone can help me ? 

Here is my two Scripts: 

- The Virtual Button Script: 

using System.Collections; using System.Collections.Generic; using UnityEngine; using Vuforia;

public class VB_Anim : MonoBehaviour, IVirtualButtonEventHandler {

    public GameObject vbBtnObj;     public Animator immoAni;

// Use this for initialization void Start () {         vbBtnObj = GameObject.Find("Vb_Rotate");         vbBtnObj.GetComponent<VirtualButtonBehaviour>().RegisterEventHandler(this);         immoAni.GetComponent<Animator>(); }

    public void OnButtonPressed(VirtualButtonBehaviour vb)     {         immoAni.enabled = true;         immoAni.Play("immo_rotate_animation");         Debug.Log("BTN Pressed the Animation is running");     }

    public void OnButtonReleased(VirtualButtonBehaviour vb)     {         immoAni.enabled = false;         Debug.Log("BTN Released the Animation is on Pause");     }

    // Update is called once per frame     void Update () {            } }

The RayCast Script: 

using UnityEngine; using System.Collections; using Vuforia;

public class ObjectHighlighter : MonoBehaviour {

public Animator anim;     public GameObject vbBtnObj;    

    // Use this for initialization     void Start () {     }

void Update () {

  foreach (Touch touch in Input.touches)   {

   Debug.Log("ok...");      if (touch.phase == TouchPhase.Began)    {     Ray ray = Camera.main.ScreenPointToRay (Input.GetTouch(0).position);                 RaycastHit hit = new RaycastHit();     if (Physics.Raycast(ray, out hit, 100000))     {

                   //My error is here                     vbanimscript.OnButtonPressed( ...);

                }

   }   }

}

}
