DropDownDataGridColumn with RadzenButton not working

I am using the RadzenDropDownDataGrid with columns. One column with name and one with an "Add" button.

It looks like I don't have a context in the click handler, like I have in the RadzenGrid?
If I remove the data parameter to for my click handler then it works.
Are there a work around?

<RadzenDropDownDataGrid
Data="@Contacts"
PageSize="15"
Count="@ReportContactsCount"
Name="Contact"
AllowFiltering="true"
FilterCaseSensitivity="FilterCaseSensitivity.CaseInsensitive"
@bind-Value="SelectedContactId"
TextProperty="Name"
ValueProperty="Id"
class="form-control-sm col-lg-8 drop-down-width">
<Columns>
    <RadzenDropDownDataGridColumn Property="Name" Title="Name" Filterable="false" Sortable="false"/>
    <RadzenDropDownDataGridColumn Filterable="false" Sortable="false" Width="60px" TextAlign="TextAlign.Center">
        <Template Context="data">
            <RadzenButton ButtonStyle="ButtonStyle.Danger" Icon="add" Size="ButtonSize.Small" Click="@(_ => AddContactToSelectedButtonClickAsync())" @onclick:stopPropagation="true"/>
        </Template>
    </RadzenDropDownDataGridColumn >
</Columns>
