signalR in blazorise - asp.net-core

Question

I'm using SignalR in asp.net core on server side and blazorise on client side. before I've used SignlaR basically just to chat and now I wanna use it to update a table when a record is inserted in some where else.
I think everything is ok on server side because as I trace it on server, it posts correct values but it does not update the table on client side. I don't know what's wrong.
here is my code on server side which is in a hub:
public async Task SendCartableUpdate(ResultData<PersonnelStationsInfo> resultData)
{
await Clients.All.SendAsync("RefreshCartable",resultData);
}
and this is how I use it on client side:
protected override async Task OnInitializedAsync()
{
//await base.OnInitializedAsync();
user = CurrentUserService.CurrentUser;
await CartableTableChangePage(1);
hubConnection = new HubConnectionBuilder()
.WithUrl(navigationManager.ToAbsoluteUri("http://localhost:15424/ProductionServiceHub"))
.Build();
hubConnection.On<ResultData<PersonnelStationsInfo>>("RefreshCartable", (_resultData) =>
{
StateHasChanged();
});
await hubConnection.StartAsync();
}
thanks for your helping

Finally I solved it and I'm so excited :)
here is how I changed my code on server side:
public async Task SendCartableUpdate()
{
await Clients.All.SendAsync("RefreshCartable");
}
and this how I changed my code on client side:
protected override async Task OnInitializedAsync()
{
//await base.OnInitializedAsync();
hubConnection = new HubConnectionBuilder()
.WithUrl(navigationManager.ToAbsoluteUri("http://192.168.2.72:1050/ProductionServiceHub"))
.Build();
hubConnection.On("RefreshCartable", () =>
{
CallLoadData();
StateHasChanged();
});
await hubConnection.StartAsync();
user = CurrentUserService.CurrentUser;
await CartableTableChangePage(1);
}
private void CallLoadData()
{
Task.Run(async () =>
{
await CartableTableChangePage(1);
StateHasChanged();
});
}
