Trigger itemupdated eventhandler when an item is Added in an SPList

Question

I have written an itemupdated event receiver for a SPList in my SP 2013 / VS 2013 solution [ on-premises] . Now I want to trigger this itemupdated event when the item is created in the SPList .But when i added an item in the splist its not triggering this itemupdated event

i have noticed that , itemupdated event and itemcheckedin event triggered for a documentlibrary[ version enabled]. but for a splist whose versioning is NOT enabled , this itemupdated event handler is not working.

How can i trigger an itemupdated eventhandler for a splistitem when an item is added into the splist ?

public class NPDListEvntRcvr : SPItemEventReceiver
{
    /// <summary>
    /// An item was added.
    /// </summary>
    public override void ItemAdded(SPItemEventProperties properties)
    {
       // base.ItemAdded(properties);
    }

    /// <summary>
    /// An item was updated.
    /// </summary>
    public override void ItemUpdated(SPItemEventProperties properties)
    {
        //base.ItemUpdated(properties);


        SPUser currUser = properties.Web.CurrentUser;

        this.EventFiringEnabled = false;

        try
        {

            // if (properties.ListTitle.ToLower() == NPDListNames.ITEMLEVELPERMISSIONSLIST.ToString())
            // {

            SPSecurity.RunWithElevatedPrivileges(delegate()
            {

                SPSite CurrentSite = new SPSite(properties.SiteId);
                SPWeb CurrentWeb = CurrentSite.OpenWeb(properties.RelativeWebUrl);

                SPList CurrentList = CurrentWeb.Lists[properties.ListId];

                SPListItem CurrentListItem;
                CurrentListItem = CurrentWeb.Lists[properties.ListId].GetItemById(properties.ListItem.ID);
                // = IsDocumentLibrary(CurrentListItem);
             //   blnIsSPList = IsSPList(CurrentListItem);
             //   blnIsFolderinDocLib = IsFolderDocumenttLibrary(CurrentListItem);

               // string authorFieldValue = CurrentListItem["Author"].ToString();
                SPFieldUserValue userValue = new SPFieldUserValue(CurrentWeb, CurrentListItem[SPBuiltInFieldId.Author].ToString());
                SPUser author = userValue.User;


                if (!CurrentListItem.HasUniqueRoleAssignments)
                {
                    CurrentListItem.BreakRoleInheritance(true);
                    CurrentWeb.AllowUnsafeUpdates = true;
