The only thing I did not see you do in the video is go to details view on your module. The MetaTitleField is activated once you click on the details you initialize the content's custom MetaTitleField. Otherwise the meta title of the page is taken as a runtime value.
Thanks Svet!
For those interested, here's my version of the solution using an MVC ActionFilter
```
public class MetaDataAttribute : ActionFilterAttribute private string metaDescription; public override void OnActionExecuting(ActionExecutingContext filterContext) var actionParameters = filterContext.ActionParameters; if (actionParameters.ContainsKey("item")) var item = actionParameters["item"] as Content; if (item != null) this.metaDescription = item.GetValue<string>("MetaDescription"); public override void OnActionExecuted(ActionExecutedContext filterContext) filterContext.Controller.ViewBag.Description = this.metaDescription;
