Custom Inspector for ScriptableObject

I want to save some data in a asset file. For this I create a new assest (conflict : ScriptableObject ). This is working but now I want to create a inspector for the asset so we can enter the data. (when you select the file ). But this isn't working. The inspector keept emty when selected.

Can somebody help me? this is my code.

To create the new asset (is working)

 using UnityEngine;
 using UnityEditor;
 using System.IO;
 using System.Collections;
 
 public class ConflictMenu: EditorWindow  {
 
 
     [MenuItem ("Assets/Create/Conflict")]
     public static void  CreateConflict () 
     {
         Conflict conf = new Conflict ();
         string path = AssetDatabase.GetAssetPath (Selection.activeObject);
 
         AssetDatabase.CreateAsset (conf, path + "/new Conflict"); 
     }
 
 }

 using UnityEngine;
 using System.Collections;
 
 
 [System.Serializable]
 public class Conflict : ScriptableObject  {
 
     public string name = "";
 
 }

Conflict (asset)

 using UnityEngine;
 using System.Collections;
 
 
 [System.Serializable]
 public class Conflict : ScriptableObject  {
 
     public string name = "";
 
 }

Inspector

 using UnityEditor;
 using UnityEngine;
 
 [CustomEditor(typeof(Conflict))]
 public class ConflictInspector : Editor {
 
     public override void OnInspectorGUI()
     {
         EditorGUILayout.TextField ("Name");
     }
 
 }
