Question Rigidbody2D.bodyType not working

Hi, I'm Julian. I have a problem changing body types via script. The thing is that when I try to change it from static to dynamic, and then back to static, it stays at dynamic.
Here's that code:

Code (CSharp):

1. public class Ball : MonoBehaviour
2. {
3.     [HideInInspector] public bool playing;
4.  
5.     // Start is called before the first frame update
6.     void Start()
7.     {
8.         playing = false;
9.         Physics2D.gravity = new Vector2(0, -9.8f);
10.         this.gameObject.GetComponent<Rigidbody2D>().bodyType = RigidbodyType2D.Static;
11.     }
12.  
13.     public void play()
14.     {
15.         playing = true;
16.         this.gameObject.GetComponent<Rigidbody2D>().bodyType = RigidbodyType2D.Dynamic;
17.     }
18.  
19.     public void reload()
20.     {
21.         playing = false;
22.         gameObject.GetComponent<Rigidbody2D>().bodyType = RigidbodyType2D.Static;
23.     }
24.  
25.     public void BackToMenu()
26.     {
27.         SceneManager.LoadScene("Level Selector", LoadSceneMode.Single);
28.     }
29. }

I don't have any idea if I'm doing something wrong or if I'm missing something.
Please help.

I am dumb:

I was calling the "reload" function on the prefab of the ball, not on the scene object.
