Why my entities are not running

Hello, I am using preview package 12 with 2018.2.02f

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Unity.Entities;
5. using Unity.Mathematics;
6.  
7. public class hybrid_instance : MonoBehaviour
8. {
9.     public MeshFilter Mesher;
10.     public bool go;
11.  
12.  
13. }
14. public class test : ComponentSystem
15. {
16.     struct Components
17.     {
18.         public hybrid_instance instance;
19.     }
20.     protected override void OnUpdate()
21.     {
22.         foreach (var e in GetEntities<Components>())
23.         {
24.             if (e.instance.go == false)
25.             {
26.                 e.instance.go = true;
27.             }
28.         }
29.     }
30. }
