OnActionExecuting / OnActionExecuted in hijacked controllers

Hey folks,

I'm trying to modify the viewmodel after an action in a hijacked controller, but OnActionExecuted (or OnActionExecuting) methods are never reached/fired.

Example of a hijacked controller:

public class PageHomeController : RenderController
{
    public PageHomeController(
        ILogger<RenderController> logger,
        ICompositeViewEngine compositeViewEngine,
        IUmbracoContextAccessor umbracoContextAccessor)
        : base(logger, compositeViewEngine, umbracoContextAccessor)
    {
    }

    public override IActionResult Index()
    {
        return CurrentTemplate(CurrentPage);
    }

    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        base.OnActionExecuting(filterContext);
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        base.OnActionExecuted(filterContext);
    }
}

I have also tried implementing the OnActionExecuting/Executed in a custom RenderController without success.

These are firing/working as expected in a custom controller.

Got the same issue. I haven't been able to get these methods firing, but managed to do a workaround by using a custom action filter:

public internal class ControllerBaseActionAttribute : ActionFilterAttribute {
       public override void OnResultExecuting(ResultExecutingContext context)
        {
            var result = context.Result as ViewResult;
            var viewModel = result?.ViewData.Model;

            base.OnResultExecuting(context);
        }
}

Then, decorate the controller with the custom filter

[ControllerBaseAction]
public class PageHomeController : RenderController

Hopefully someone else can find a solution to get the action methods fired.

In v10.4.0 at least, you can do
```
public override async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)
{
}
```
