Hey you can try to create a clear cache actionfilter and then decorate the specified Action(the one that adds item to the list) in the controller with the action name and once done you can fill the list again to be cached the actionfilter would be something like given below.

you can dynamically clear the cache. But if your requirement is as such then either reduce the time duration for output cache else use Donut Caching..
Thanks

C#

public class ClearCache : ActionFilterAttribute
{
    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        filterContext.HttpContext.Response.Cache.SetExpires(DateTime.UtcNow.AddDays(-1));
        filterContext.HttpContext.Response.Cache.SetValidUntilExpires(false);
        filterContext.HttpContext.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
        filterContext.HttpContext.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        filterContext.HttpContext.Response.Cache.SetNoStore();

        base.OnResultExecuting(filterContext);
    }
}
