Integrate Blazor-Component in Razor-Page (*.cshtml) - Events

i want to implement a Blator-Component within a EventCallBack in a razor-Page (*.cshtml). Currently the component is shown and i can click the buttons inside the component with the correct reaction of the component.

Now i want to get the events of the component and call some functions in the razor-file. But this does not work.

My Blazor-Component has a EventCallBack like this:

[Parameter]public EventCallback<bool> OnValidate { get; set; }

and is triggert like this:

OnValidate.InvokeAsync( false );

My razor-page implement the component like this:

<component type="typeof(MyBlazorComponent)" render-mode="ServerPrerendered"           param-Width=200           param-Height=50           param-OnValidate="@(EventCallback.Factory.Create<bool>(this, HandleAction))" />

and the called function is

void HandleAction( bool actionResult ){    t = actionResult;}

I hoped that the function HandleAction is called when the EventCallBack is invoked but it does not.
