What are Best Practices for Vive Controller input with regard to dPad input and event functions?

Unity Engine

Complete Newbie to both Unity and SteamVR (and C# for that matter). I have managed to get input from the dPad to my debug log.

I am currently seeing anywhere from 12 to 19 responses for every press of the button. I really only one it to trigger once as this is ultimately going to be tied to functionality that will teleport the player to a fixed spot adjacent to their current position. My hunch is, Update may not be the best place to grab this input. Of course, its more likely I am going about this entirely incorrectly. At any rate, here is the script I am using. Any advice would be appreciated.

using UnityEngine;
using System.Collections;

public class MovementController : MonoBehaviour {

    private SteamVR_Controller.Device controller { get { return SteamVR_Controller.Input((int)trackedObj.index); } }
    private SteamVR_TrackedObject trackedObj;

    public bool dUp = false;
    public bool dDown = false;
    public bool dLeft = false;
    public bool dRight = false;

    void Start ()
    {
      trackedObj = GetComponent<SteamVR_TrackedObject>();
    }

    void Update()
    {
        if (controller == null)
        {
            Debug.Log("Controller not initialized");
            return;
        }

        if (controller.GetPress(SteamVR_Controller.ButtonMask.Touchpad))
        {
            if (controller.GetAxis(Valve.VR.EVRButtonId.k_EButton_SteamVR_Touchpad).y > 0.5f)
            {
                dUp = true;
                Debug.Log(trackedObj.index + " Movement Dpad Up");
            }

            if (controller.GetAxis(Valve.VR.EVRButtonId.k_EButton_SteamVR_Touchpad).y < -0.5f)
            {
                dDown = true;
                Debug.Log(trackedObj.index + " Movement Dpad Down");
            }

            if (controller.GetAxis(Valve.VR.EVRButtonId.k_EButton_SteamVR_Touchpad).x > 0.5f)
            {
                dRight = true;
                Debug.Log(trackedObj.index + " Movement Dpad Right");
            }

            if (controller.GetAxis(Valve.VR.EVRButtonId.k_EButton_SteamVR_Touchpad).x < -0.5f)
            {
                dLeft = true;
                Debug.Log(trackedObj.index + " Movement Dpad Left");
            }
        }
    }
}

The problem is arising from the use of GetPress(). This will trigger every frame while the button is being pressed. It seems that you would be much better served using GetPressUp() or GetPressDown() depending on if you want the press or release of the touch pad to trigger the appropriate action.
