[Command] only working on host

Hi im trying to share a list over network but it only seams to work on the host

i call this when i die

 [Command]
     void CmdSpawnBody(){
         GameObject body = (GameObject)Instantiate (DeathObject);
         body.transform.position = new Vector3 (this.transform.position.x,this.transform.position.y,0.01f);
         NetworkServer.Spawn (body);
         for(int i = 0;i < GetComponent<Inventory>().inventory.Count;i++){
             body.transform.GetComponent<Container> ().CmdUpdateItems (
                 GetComponent<Inventory> ().inventory [i].ItemName
                 ,GetComponent<Inventory> ().inventory [i].ItemID
                 ,GetComponent<Inventory> ().inventory [i].ItemAmount
                 ,GetComponent<Inventory> ().inventory [i].itemType
                 ,GetComponent<Inventory> ().inventory [i].Sprite
                 ,GetComponent<Inventory> ().inventory [i].Stackable
                 ,i);
 
         }
     }

which accesses this funtion on the body object

 [Command]
     public void CmdUpdateItems(string name,int id,int amount,string type,string sprite,bool stack, int place){
         container.Add (new ContainerItem());
         container [place].ItemName = name;
         container [place].ItemID = id;
         container [place].ItemAmount = amount;
         container [place].itemType = type;
         container [place].Sprite = sprite;
         container [place].Stackable = stack;
     }

why does this only work on the host. when another player dies the list isnt added to. am i doing something wrong?
