Why is my ASP.NET Web API ActionFilterAttribute OnActionExecuting not firing?

Question

I\'m trying to implement what\'s seen here: http://www.piotrwalat.net/nhibernate-session-management-in-asp-net-web-api/ but I\'m having an issue with my NhSessionManag

Here is the complete Implementation:

public class AllowCrossSiteJsonAttribute : System.Web.Mvc.ActionFilterAttribute
{
    public override void OnActionExecuted(System.Web.Mvc.ActionExecutedContext filterContext)
    {
        if (filterContext.HttpContext != null && filterContext.HttpContext.Response != null && filterContext.HttpContext.Request != null && filterContext.HttpContext.Request.UrlReferrer != null)
        {
            var allowedCrossDomains = TypeSafeConfigurationManager.GetValueString("allowedCrossDomains", "none");
            var allowedHosts = allowedCrossDomains.Split(',');

            var requestHost =  filterContext.HttpContext.Request.UrlReferrer.GetLeftPart(UriPartial.Authority);
            if (allowedHosts.Contains(requestHost.ToLower()))
            {
                filterContext.HttpContext.Response.Headers.Add("Access-Control-Allow-Origin", requestHost);
            }
        }

        base.OnActionExecuted(filterContext);
    }
}
public class AllowCrossSiteJsonForWebApiAttribute : ActionFilterAttribute
{
    public override void OnActionExecuted(HttpActionExecutedContext actionExecutedContext)
    {
        if (actionExecutedContext.Response != null && actionExecutedContext.Request != null &&
            actionExecutedContext.Request.Headers.Referrer != null)
        {
            var allowedCrossDomains = TypeSafeConfigurationManager.GetValueString("allowedCrossDomains", "none");
            var allowedHosts = allowedCrossDomains.Split(',').ToList();

            var requestHost = actionExecutedContext.Request.Headers.Referrer.GetLeftPart(UriPartial.Authority);

            if (allowedHosts.Contains(requestHost.ToLower()))
            {
                actionExecutedContext.Response.Headers.Add("Access-Control-Allow-Origin", requestHost);
            }

            base.OnActionExecuted(actionExecutedContext);
        }
    }
}
