TypeHead on change refresh DataGrid?

[PhotoSonic]

I have page with following

        protected override async Task OnInitializedAsync()
        {
            accessPoints = await GetAccessPoints();
            SelectedAccessPoints = accessPoints.ToList();
            visits = await GetVisitsByAccessPoints(SelectedAccessPoints);
        }

accessPoints is data for my typehead

                            <Typeahead SearchMethod="@SearchAccessPoints"
                                       Items="accessPoints"
                                       @bind-Values="@SelectedAccessPoints"
                                       Placeholder="Access point">
                                <SelectedTemplate Context="accessPoint">
                                    @accessPoint.Name
                                </SelectedTemplate>
                                <ResultTemplate Context="accessPoint">
                                    @accessPoint.Name
                                </ResultTemplate>
                            </Typeahead>

visits are my data for my datagrid.

<DataGrid Data="visits" class="table table-hover" @ref="Grid">

Can you pls tell me how to call onchage event on typehead and then call method for refreshing the grid with new visit data ( await GetVisitsByAccessPoints(SelectedAccessPoints);) ?
