Unity for OculusGo: Move an object along the z axis by touchpad

I have written a script to pick an object with a rigidbody component by the ray casted from the controller and move it around. I make the object, the child of the controller to move it in the scene then. I already have a script to detect the object by the ray casted from a controller, picking it up and moving it up and down and left and right with the controller.

Now , I want to make that selected object along the z-axis by using the touchpad of oculus go. However I am not sure how to do it. This is the function i am using it to attach to the parent:

Code (CSharp):

1.  public virtual void Store(Transform NewParent)
2.     {
3.         //The following stops the object being effected by physics while it's in the players hand
4.         rb.isKinematic = true;
5.         //And fixes it to the new parent it is given by the player script to follow.
6.         transform.parent = NewParent;
7.         //It then resets it's position and rotation to match it's new parent object
8.         //transform.localRotation = Quaternion.identity;
9.         //transform.localPosition = Vector3.zero;
10.     }

and then i use it in the pointer class to attach it to the ray:

Code (CSharp):

1. void Intract()
2.     {
3.         //We set up the input "OculusPrimaryIndexTrigger" in the Input manager
4.         if (OVRInput.GetDown(OVRInput.Button.PrimaryIndexTrigger))
5.         {
6.             selectVisual.ClearObject();
7.             //Check if you are holding something you can throw first
8.             if (inHand != null)
9.             {
10.                 inHand.Release(controllerRef.forward, throwForce);
11.                 inHand = null;
12.                 //We do this check here to prevent Errors if you have nothing selected
13.             }
14.             else if (selectedObject != null)
15.             {
16.                 //Check if you can pick up the selected object second
17.                 if (selectedObject.GetComponent<PickUp>())
18.                 {
19.                     //Beacuse PickUp is a child of PropBase, we can ask InHand to store selectedObject as PickUp, rather than use GetComponent
20.                     inHand = selectedObject as PickUp;
21.                     inHand.Store(holdingRef);
22.                     //If non of the above were valid then simple call the trigger function of the selected object
23.                 }
24.                 else
25.                 {
26.                     selectedObject.Trigger();
27.                 }
28.             }
29.             //If you have a object that you need to hold down a button to intract with
30.         }
31.      
32.         else if (pointerOver != null)
33.         {
34.             if (pointerOver.GetComponent<PropBase>())
35.             {
36.                 selectedObject = pointerOver.GetComponent<PropBase>();
37.             }
38.             else
39.             {
40.                 selectedObject = null;
41.             }
42.         }
43.         else
44.         {
45.             selectedObject = null;
46.         }
47.  
48.     }
49.  
50. }

If anyone could point me in a right direction or help me with this, I would greatly appreciate it!

Thanks in advance
