RPC activating gameobject on Host instead of on the Client

Hi guys. I am trying to make a player put on a helmet when clicking on it. There is a helmet on the ground tagged as "Helmet", and the another helmet on the player prefab with the renderers deactivated so it is invisible, tagged as "Object".

What I try to do with my code is to click on the helmet on the floor, make it unactive, and then set the renderers on for the helmet on the head of the player that has clicked.

What is happening to me is that when my Host clicks the helmet on the floor everything works perfect, but when it's the Client who clicks, the helmet that turns active it is still the one on the Host head.

PD: This script is turned on on for the local player through another script that enables it using the function "OnStartLocalPlayer"

Here's my script :D

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 using UnityEngine.Networking;
 
 public class Helmet : NetworkBehaviour {
 
     public Transform cameraTransform;
 
     GameObject helmetFloor;
     GameObject helmetHead;
     // Use this for initialization
     void Start () {
         
     }
     
     // Update is called once per frame
     void Update () {
                
 
         RaycastHit hit;
         Vector3 rayPos = cameraTransform.position + cameraTransform.forward * 1f;
         Debug.DrawRay(rayPos, cameraTransform.forward * 5f, Color.green, 0.5f);
 
         if (Physics.Raycast(rayPos, cameraTransform.forward, out hit, 5f))
         {
             if (hit.transform.tag == "Helmet")
             {              
 
                 if (Input.GetMouseButtonDown(0))
                 {                    
                     CmdHelmet();
                 }
             }
         }
 
     }
 
     [Command]
     void CmdHelmet()
     {
               
         RpcHelmet();
     }
 
     [ClientRpc]
     void RpcHelmet()
     {
         helmetFloor = GameObject.FindGameObjectWithTag("Helmet");
         helmetHead = GameObject.FindGameObjectWithTag("Object");
         helmetFloor.SetActive(false);
         helmetHead.GetComponent<Renderer>().enabled = true;
     }
 }

This is for my thesis at university (yeah, it got weird), so all the help would be much appreciated. Thanks!
