How to GroundPlane Change  place Object LocalScale?

this is code .

using UnityEngine;
using System.Collections;
   
public class NewBehaviourScript : MonoBehaviour
{   
    GameObject rotater;
  
    void Start ()
    {
        rotater = GameObject.Find("GameObject");
    }
   
    void Update()
    {
   
    }
   
    void OnGUI()
    {
        if (GUI.RepeatButton (new Rect (250, 250, 250, 250), "Check here"))
        {
            rotater.gameObject.transform.localScale += new Vector3(0.1f,0.1f,0.1f);
        }
    }      
}
 

When I press the button, the scale of the object changes but the size of the placed object does not change.

Help me thanks.
