Translate more than one object on update with the same function

Hi,

I wanna add translate on some GameObjects, but with my code, when one object start to move, the last one stop.

How do i make the previous object keep the move?

My code:

 void Update () {
     MoveGameObject (Draggable.objectClicked);
 }

 void MoveGameObject(string objectClickedToMove) {
     GameObject objectToMove = GameObject.Find (objectClickedToMove);
     if (moveable) {
         directions = Draggable.positionOnMouseDown - Draggable.positionOnMouseUp;
         if (directions < 0) {
             objectToMove.transform.Translate (Vector3.right * moveSpeed * Time.deltaTime);
         } else if (directions > 0) {
             objectToMove.transform.Translate (Vector3.left * moveSpeed * Time.deltaTime);
         }
     }
 }
