How can I have multiple inspector inside of a custom inspector

Hello all!

I´m having trouble creating a custom inspector and drawing others inspectors based on an array, inside it.

Im able to add new elements to the array and draw the new inspector but the general inspector is not updated instantly

![alt text][1]

The Add button is working but the list is not updated. Same for the remove button ( - )

The ActionGroupBehaviour have an array of actions (type of ScriptableObject):

 [SerializeField] private ActionSO[] _actions = new ActionSO[0];

And on the CustomEditor script I iterate over this array and create the editors:

     private VisualElement CreateActionsContainer(ActionSO[] actions)
     {
         VisualElement actionContainer = new VisualElement();
         actionContainer.AddToClassList("actions-container");

         VisualElement actionInspector = null;
         for (int i = 0; i < actions.Length; i++)
         {
             actionInspector = CreateActionEditor(actions[i]);
             actionContainer.Add(actionInspector);
         }
         return actionContainer;
     }

And this is the action executed when the Add button is clicked:

 private Action OnActionAdded()
         {
             return () =>
             {
                 ActionSO newAction = CreateInstance(_selectedAction) as ActionSO;
                 _actions.AddToObjectArray(newAction);                
                 serializedObject.ApplyModifiedProperties();
             };
         }

I guess my problem is related to binding the array but I dont know have to address it.

Sorry for my english.
