Why is this not shown in the inspector?

Unity Engine

This list is not showing on the inspector and afaik inspector supports polymorphism. So I don’t understand why it s not shown in the inspector.

[Serializable]
    public class ObservedList<T> : List<T>
    {
        public event Action<int> Changed = delegate { };
        public event Action<T> Added = delegate { };
        public event Action<T> Removed = delegate { };
        public event Action Updated = delegate { };

        public new void Add(T item)
        {
            base.Add(item);
            Added(item);
            Updated();
        }

        public new void Remove(T item)
        {
            Removed(item);
            base.Remove(item);
            Updated();
        }

        public new void AddRange(IEnumerable<T> collection)
        {
            base.AddRange(collection);

            foreach (var item in collection)
                Added(item);

            Updated();
        }

        public new void RemoveRange(int index, int count)
        {
            for (int i = index; i < count; i++)
                Remove(this[index]);

            base.RemoveRange(index, count);
            Updated();
        }

        public new void Clear()
        {
            foreach(var item in this)
                Remove(item);

            base.Clear();
            Updated();
        }

        public new void Insert(int index, T item)
        {
            base.Insert(index, item);
            Added(item);
            Updated();
        }

        public new void InsertRange(int index, IEnumerable<T> collection)
        {
            base.InsertRange(index, collection);

            foreach (var item in collection)
                Added(item);

            Updated();
        }

        public new void RemoveAll(Predicate<T> match)
        {
            base.RemoveAll(match);
            Updated();
        }


        public new T this[int index]
        {
            get { return base[index]; }
            set
            {
                base[index] = value;
                Changed(index);
            }
        }
    }

public ObservedList<string> Test;

Is there any other way to detect changes on a list on inspector?
