Call Class instance methods from JavaScript functions in Blazor

The component should keep a reference to the DotNetObjectReference we create.
The component should implement IDisposable and dispose our DotNetObjectReference.

@page "/"
@inject IJSRuntime JSRuntime
@implements IDisposable

<h1>Text received</h1>
<ul>
  @foreach (string text in TextHistory)
  {
    <li>@text</li>
  }
</ul>

@code
{
  List<string> TextHistory = new List<string>();
  DotNetObjectReference<Index> ObjectReference;

  protected override async Task OnAfterRenderAsync(bool firstRender)
  {
    await base.OnAfterRenderAsync(firstRender);
    if (firstRender)
    {
      ObjectReference = DotNetObjectReference.Create(this);
      await JSRuntime.InvokeVoidAsync("BlazorUniversity.startRandomGenerator", ObjectReference);
    }
  }

  [JSInvokable("AddText")]
  public void AddTextToTextHistory(string text)
  {
    TextHistory.Add(text.ToString());
    while (TextHistory.Count > 10)
      TextHistory.RemoveAt(0);
    StateHasChanged();
    System.Diagnostics.Debug.WriteLine("DotNet: Received " + text);
  }

  public void Dispose()
  {
    GC.SuppressFinalize(this);

    if (ObjectReference != null)
    {
      //Now dispose our object reference so our component can be garbage collected
      ObjectReference.Dispose();
    }
  }
}

var BlazorUniversity = BlazorUniversity || {};
BlazorUniversity.startRandomGenerator = function (dotNetObject) {
  return setInterval(function () {
    let text = Math.random() * 1000;
    console.log("JS: Generated " + text);
    dotNetObject.invokeMethodAsync('AddText', text.toString());
  }, 1000);
};
BlazorUniversity.stopRandomGenerator = function (handle) {
  clearInterval(handle);
};
