Inline datagrid insert not working for generated page

Shows loaded datagrid data but with no action when add button is clicked.

NET 5.0. WebAssemblye. New version with new code generated.
protected async System.Threading.Tasks.Task Button0Click(MouseEventArgs args)
{
await this.grid0.InsertRow(new RadzerCrm3.Models.Crm.OpportunityStatus());
}
Button clicked is called but new line is not displayed

Thanks for letting us know - we will do our best to include fix in some of our next updates. Until then you can use CRUD pages template.
