Input.ResetInputAxes Doesn't Stop From Moving?

I've added that line of code hoping to stop my character from moving, but it only stops my camera from moving. I can still use WASD to walk around and space to jump and everything. It slows down the movement but it doesn't completely stop it. When I use it in ThirdPersonController.js it works but when I use it in my PlayerHealth.cs script, it doesn't work. Here is my code for PlayerHealth.cs, (The file i'm trying to get it to work in)

 using UnityEngine;
 using System.Collections;
 
 public class PlayerHealth : MonoBehaviour {
     public int maxHealth = 100;
     public int curHealth = 100;
     public GameObject Enemy;
     public float healthBarLength;
     private bool isControllable = true;
     
     void Start () {
         healthBarLength = Screen.width / 2;
     }
     
     
     void Update () {
         AddjustCurrentHealth(0);
         if (!isControllable)
         {
             // kill all inputs if not controllable.
             Input.ResetInputAxes();
         }
         
     }
 
     
     
     void OnGUI(){
         GUI.Box(new Rect(100, 200, healthBarLength, 20), curHealth + "/" + maxHealth);    
     }
     
     
     public void AddjustCurrentHealth(int adj) {
         curHealth += adj;    
         
         if(curHealth < 0)
             curHealth = 0;
         
         if(curHealth > maxHealth)
             curHealth = maxHealth;
         
         if(maxHealth < 1)
             maxHealth = 1;
         
         healthBarLength = (Screen.width / 2) * (curHealth / (float)maxHealth);
 
         if(curHealth <= 0) {
             animation.CrossFade("Dead");
             isControllable = false;
         }
 
         if (curHealth <= 0) {
                         DestroyImmediate(Enemy, true);
                 }
     }
 }
