Blazor. Dynamic update datagrid column title

Radzen Studio Blazor Server
1

Hello!
I have problem with dynamic update datagrid column title.

<RadzenDatePicker TValue="DateTime?" Inline="true" Change="@(args => Change(args, "Calendar", "MM/dd/yyyy"))" />

void Change(DateTime? value, string name, string format)
{
events.Add(DateTime.Now, $"{name} value changed to {value?.ToString(format)}");
currentDay = (DateTime)value;
titleCol = reportService.GetColTitleRateDayOfDay(currentDay);

Names are updated late for one date change event in the calendar.
