Blazor Server-Side not re-rendering component after event is fired !

As described in the title,i can’t see any re-rendering after ‘onclick’ is fired

To Reproduce

Steps to reproduce the behavior:

1. Using this version of ASP.NET Core ‘3 preview 7’
2. Run this code

protected virtual void BuildCompnent(RenderTreeBuilder builder)
{
...

builder.AddContent(seq, _viewProperty.PropertyValue ?? "--SELECT--");

...

     foreach (var item in SelectionDictionary)
                    {                   
                        builder.OpenElement(++seq, "a");
                        builder.AddAttribute(seq, "class", "font-weight-light btn-sm dropdown-item " + (item.Value == _viewProperty.PropertyValue ? "active" : ""));
                        builder.AddAttribute(seq, "onclick", () => ItemClicked?.Invoke(item.Key)); 
                        //builder.SetUpdatesAttributeName("onclick"); --> tried it but no help
                        builder.AddContent(seq, item.Value.ToString());
                        builder.CloseElement();
                   }
...
}

1. The Action ‘ItemClicked’ is reached by the debugger , but component not showing “re-rendering” the selected item

Expected behavior

It should re-render the component by default when ‘onclick’ event is fired

Additional context

BTW this code was working like a charm in blazor 0.7 server-side but after updating to latest version…things got crackly

how could i know the future ?! like how many item in SelectionDictionary ?!

In the linked blog post, it explains how you should handle this to avoid the seq++ code.
