                                selectionModel.clear();
                                selectionModel.setSelected(gestionHabilitationsItem, true);                                    cellTableFonctions.setSelectionModel(selectionModel);                                    leftCellTable.setSelectionModel(selectionModel);
                            }
                        });
                    }
                }
            });

With this code i have two click one for select the row and another for change the state of the checkbox. How can i combine it? Appreciate any suggestions.
