C# EdgeCollider2D Points Not Updating Continuously

I'm trying to make a script that creates a GameObject with a Line Renderer, a Edge Collider2D and have the scripted gameobject attach to another gameobject called go. I was able to set the Line Renderer's positions. But when I try to set the Edge Collider2D's points it only updates once and not continuously as it should be in the Update function. Is there a different method of setting the Edge Collider2D's points that updates continuously?

 using UnityEngine;
 using System.Collections;
 using System.Collections.Generic;
 public class LineConnect : MonoBehaviour {
     public GameObject go;
     private EdgeCollider2D col;
     private LineRenderer line;
     void Awake() {
         col = GetComponent<EdgeCollider2D>();
         line = GetComponent<LineRenderer>();
     }
     
     // Use this for initialization
     void Start () {
     
     }
     
     // Update is called once per frame
     void Update () {
         Vector3 linePos = new Vector3 (transform.parent.position.x,transform.parent.position.y - 0.45f, transform.parent.position.z);
         Vector2[] colPoints = new Vector2[]{new Vector2(0,0.5f),new Vector2(go.transform.position.x,go.transform.position.y)};
         col.points = colPoints;
         line.SetPosition(0, linePos);
         line.SetPosition(1, go.transform.position);
     }
 }
