My script is working only once. How can I make it works evertime. Gameobject is button

Code (CSharp):

1. using System.Collections.Generic;
2. using UnityEngine;
3. using UnityEngine.UI;
4.  
5.  
6. public class Cooldown : MonoBehaviour
7. {
8.  
9.  
10.     float timer = 0;
11.  
12.     public GameObject Enable_Disable;
13.  
14.  
15.    
16.     public void Enable()
17.     {
18.  
19.         Enable_Disable.SetActive(true);
20.  
21.  
22.     }
23.  
24.  
25.     public void Disable()
26.  
27.     {
28.         Enable_Disable.SetActive(false);
29.  
30.     }
31.  
32.  
33.     void Update()
34.     {
35.  
36.  
37.         timer = timer + Time.deltaTime;
38.  
39.         if (timer > 6)
40.         {
41.             Enable_Disable.SetActive(true);
42.          
43.  
44.         }
45.     }
46.  
47.  
48. }

 

After calling Enable_Disable.SetActive, reset timer value.
