Page Event is not saving into xDB

Question

I want to save some information about that page that has been clicked by the user so I register a page event on processItem pipeline for this I did below code:

  public class RegisterCustomPageEvents : ProcessItemProcessor
    {
        public override void Process(ProcessItemArgs args)
        {

            foreach (TrackingField trackingParameter in (IEnumerable<TrackingField>)args.TrackingParameters)
                TrackingFieldProcessor.ProcessEvents(args.Interaction, trackingParameter);

            if (!Tracker.Enabled || Tracker.Current == null || !Tracker.Current.IsActive)
            {
                return;
            }

            FireCustomEvent(args);
        }

        private void FireCustomEvent(ProcessItemArgs args)
        {
            var myPageTemplateId = "{ED0B99D5-4992-429F-84FE-F8F3D902CAB5}";

            if (args.Item == null || Context.Item.TemplateID.ToString() != myPageTemplateId)
            {
                return;
            }
            var ev = Tracker.MarketingDefinitions.PageEvents[Guid.Parse("{059A1829-DD32-47B6-8EA6-BEEFAC98DC6E}")];

            if (ev != null)
            {
                var pageData = new PageEventData(ev.Alias, ev.Id);

                pageData.Text = "Event";

                var fullUrl = System.Web.HttpContext.Current.Request.Url.AbsoluteUri;

                pageData.CustomValues.Add("Url", fullUrl);
                pageData.CustomValues.Add("PageTemplateId", args.Item.TemplateID.ToString());
                pageData.CustomValues.Add("ItemVersion", args.Item.Version.Number);

                pageData.ItemId = args.Item.ID.ToGuid();

                try
                {
                    Tracker.Current.CurrentPage.Register(pageData);
                }
                catch (Exception ex)
                {
                    Log.Error("Unable to fire custom event", ex, this);
                }
            }
        }
}

            </processItem>

My issue is that I am not able to see page events in Interactions table. I tried to abandon the session.
