ToggleGroup in a GXT ColumnConfig - gwt

Question

I'm using a ColumnConfig for presenting and editing data. For the gender I wann to have RadioButtons which where defined by an enumeration.
In every row i want to have:
id | (x) male ( ) female | name | date
The only way I have found was adding a "button" with defined rendering code. But there I cannot get the values or actions for pushed radio.
ColumnConfig<SomeValueGto, String> begIdCol = createColumnConfig(begIdProvider, "Id", sizeBegId);
//gender
ColumnConfig<SomeValueGto, GenderCode> genderCol = createColumnConfig(GRID_PROPERTIES.sex(), "Sex*", sizeGender);
ColumnConfig<SomeValueGto, String> nameCol = createColumnConfig(GRID_PROPERTIES.name(), "Name*", sizeName);
ColumnConfig<SomeValueGto, Date> birthdateCol = createColumnConfig(GRID_PROPERTIES.birthdate(), "Birthdate*", sizeBirthdate);
DateCell gebCell = new DateCell(DateTimeFormat.getFormat("dd.MM.yyyy"));
geburtsdatumCol.setCell(gebCell);
//add fields to the row
List<ColumnConfig<SomeValueGto, ?>> columnList = new ArrayList<ColumnConfig<SomeValueGto, ?>>();
columnList.add(begIdCol);
columnList.add(genderCol);
columnList.add(nameCol);
columnList.add(birthdateCol);
ColumnModel<SomeValueGto> cm = new ColumnModel<SomeValueGto>(columnList);
ListStore<SomeValueGto> gridStore = new ListStore<SomeValueGto>(GRID_PROPERTIES.id());
myGrid = new SLGrid<SomeValueGto>(gridStore, cm);
// empty entries. default ids 1/2/3
myGrid.getStore().add(new SomeValueGto(1));
myGrid.getStore().add(new SomeValueGto(2));
myGrid.getStore().add(new SomeValueGto(3));
final GridInlineEditing<SomeValueGto> editing = new GridInlineEditing<SomeValueGto>(myGrid);
editing.setErrorSummary(false);
editing.addEditor(nameCol, new TextField());
final SLDateField dateField = new SLDateField("date", false, true);
editing.addEditor(geburtsdatumCol, new Converter<Date, Date>() {.....}, dateField);
The helper createColumnConfig:
private <T> ColumnConfig<SomeValueGto, T> createColumnConfig(ValueProvider<SomeValueGto, T> aValueProvider, String aHeader, int aWidth) {
ColumnConfig<SomeValueGto, T> columnCol = new ColumnConfig<SomeValueGto, T>(aValueProvider);
columnCol.setHeader(aHeader);
columnCol.setWidth(aWidth);
columnCol.setMenuDisabled(true);
return columnCol;
}
Does anyone have already solved a problem like this?

GXT Grids uses com.google.gwt.cell.client.Cell to render data in the grid. I don't think the kind of cell you want exist in GXT. So I think you will have to implement your own cell. You can take example of ColorPaletteCell, which allow the user to select a color from the cell itself.
So you will need to implement the render and onBrowserEvent methods to manage your radio buttons and what append when the user click on it.
