Blazor isnt re-rendering Component after receiving a Paramameter(Hashset) from Service

My Blazor component is not being re-rendered after receiving a new value for its hashset parameter from a service I have implemented. The parameter is set by an event in the service.

This is the main page where my component in question "GenericGridComponent" is located. When rendering the page, a database query is called by await Task.Run(() => DataExchange.AccessData<fcPersons>());, which stores a hashset from a database in the DataExchange service.

@inject DataExchange DataExchange@rendermode InteractiveServer<GenericGridComponent        T="fcPersonen"></GenericGridComponent>@code {    protected async  override OnAfterRender(Boolean firstRender)    {        if (firstRender == true)        {            await Task.Run(() => DataExchange.AccessData<fcPersonen>());        }    }}

In the GenericGridComponent, an event is bound in OnAfterRender, which assigns a new value to the hashset parameter Elements by the service. The value is successfully assigned to the parameter, but this does not re-render the user interface of my component. In this case, I would like to dispense with the StateHasChanged() method, because as far as I know, Blazor should automatically register a change to a parameter and re-render the specific content.

@typeparam T where T :class, new()@inject DataExchange DataExchange@using System.Reflection@if (Elements != null){<table class="table table-bordered"><thead class="thead"><tr>            @foreach (PropertyInfo propertyInfo in Elements.First().GetType().GetProperties())            {<th scope="col"><div style="width:fit-content;"><p>@propertyInfo.Name</p></div></th>            }</tr></thead><tbody><Virtualize TItem="T" Context="obj" Items="Elements"><tr>                    @foreach (PropertyInfo propertyInfo in obj.GetType().GetProperties())                    {<td>@propertyInfo.GetValue(obj)</td>                    }</tr></Virtualize></tbody></table>}@code {    protected override void OnAfterRender(Boolean firstRender)    {        if (firstRender == true)        {            DataExchange.DataChanged += DataChanged;        }    }    private void DataChanged()    {        Elements = DataExchange.GetData<T>();    }    private HashSet<T>? Elements { get; set; }}

It was expected that the component would redraw itself due to the change in the bound property.
