How to move an object over the network. If only the client controlls/moves that non-player object?

Hello all, I need some help with my code to move an object over the network. in the code i have, the object that i want to move moves on the network and on the clients. This is done by use a command and a RPC call to a syncvar (Vector3) on my movingobject. The strange thing is that that same syncvar is set to the right value i want with the command and RPC but then it also go back to the old value again. So the object goes back to its old position. (not wat i want). i cant find it where that is happening that the syncvar is going back to its old position. so i want a object that can move and its getting controlled by a client. I think i do something wrong in the code that i have and i hope someone can help me with wat i am doing wrong here.

This is the script on the player object for the client:

 public Vector3 newPosition;
 public GameObject gameObjectTodrag;
   
 void Awake()
     {
         gameObjectTodrag= GameObject.FindGameObjectWithTag("movingObject");
         newPosition = gameObjectTodrag.transform.position;
     }
 
 void Update()
     {
         if (isClient && isLocalPlayer)
         {
             MyMove();
         }
     }
 
  void MyMove()
    {
      CmdMoveTouchOnServer(gameObjectTodrag,  movingObjectsWithPosition[gameObjectTodrag]);   
    }
 
 [Command]
 void CmdMoveTouchOnServer(GameObject obj, Vector3 newPos)
     {
         objNetId = obj.GetComponent<NetworkIdentity>();        
         if (!hasAuthority)
         {
             objNetId.AssignClientAuthority(connectionToClient);   
         }
          RpcMoveTouchOnServer(obj, newPos);
     }
 
 [ClientRpc]
 void RpcMoveTouchOnServer(GameObject obj, Vector3 newPos)
     {
         obj.GetComponent<MoveObject>().newPosition = newPos;      
     }

On the MoveObject script it will handle the movement to look at the "newPosition" defined like this:

  [SyncVar]
     public Vector3 newPosition;
