GearVR Line Renderer

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

public class NewBehaviourScript1 : MonoBehaviour {

    // Use this for initialization
    private Transform childObject;
    private ParticleSystem objectParticles;
    private LineRenderer objectLineRenderer;
    void Start () {
        childObject = gameObject.transform.Find("EventHohl");
        objectLineRenderer = childObject.GetComponent<LineRenderer>();
    }
	
	// Update is called once per frame
	void Update () {
        if (OVRInput.Get(OVRInput.Button.Two));
            objectLineRenderer.enabled = false;

    }
}

I'm making VR video player with controls based on gearvr controller and I want to add function that will remove line renderer(because it disturbs when you watch video) and turn it back on touchpad click, or swipe up/down, idk. I tried to do this, but it couldn't work, upper you can see my code. EventHohl is eventsystem to which I attached linerenderer
