VaadinTestBench Grid ComponentRenderer problem

Hi, Basically i’m creating column like this:
addColumn(new ComponentRenderer<Button, Customer>(Button::new, (btn, item) → {
btn.setText(“Test2”);
})).setHeader(“Actions”).setFrozenToEnd(true).setAutoWidth(true).setFlexGrow(0).setTextAlign(ColumnTextAlign.CENTER);
Then trying to test:
Grid<?> grid = $view(Grid.class).first(); GridTester<? extends Grid<?>, ?> gridTester = test(grid);

    Button cellComponent = (Button) gridTester.getCellComponent(0, 12);
    test(cellComponent).click();

Finally getting: java.lang.IllegalStateException: Button[caption=‘Test2’] is not usable
