Java FXML Add ObservableList to TableView - javafx

Question

I can't display my Observable List in the table view. I don't get any error. I was check if Observable List and List have value and everything looks fine. I don't have any idea where is a problem. I was try to add ValueFactory also in FXML code and it still don't work
FXML
<TableView fx:id="laczenie" layoutX="641.0" layoutY="52.0" prefHeight="415.0" prefWidth="438.0">
<columns>
<TableColumn prefWidth="75.0" text="Wezly" fx:id="C1" >
</TableColumn>
<TableColumn prefWidth="361.0" text="MozliwePolaczenia" fx:id="C2">
</TableColumn>
</columns>
</TableView>
JavaFx Controller
public class FXMLDocumentController implements Initializable {
private JavaFXApplication4 mainApp;
public List<Krawendzie> list = new ArrayList<Krawendzie>();
#FXML
private TableColumn C1;
#FXML
private TableColumn C2;
#FXML
private TableView<Krawendzie> laczenie;
#FXML
private Label label;
#FXML
private ComboBox<String> combo;
#FXML
private GridPane Scena;
#FXML
private void handleButtonAction(ActionEvent event) {
System.out.println("You clicked me!");
label.setText("Hello World!");
}
#Override
public void initialize(URL url, ResourceBundle rb) {
C1.setCellValueFactory(new PropertyValueFactory<Krawendzie,Integer>("Wezel"));
C2.setCellValueFactory(new PropertyValueFactory<Krawendzie,Integer>("Mozliwosci"));
combo.getItems().addAll("2","3","4","5","6","7","8");
list.removeAll(list);
}
#FXML
private void itemselected(ActionEvent event){
}
#FXML
private void rysuj(ActionEvent event) {
rysuj2(Integer.parseInt(combo.getValue()));
}
private void rysuj2(Integer Ilosc){
list.removeAll(list);
Scena.getChildren().clear();
laczenie = new TableView<Krawendzie>();
File f = new File("././Image/Imapges1.jpg");
Image image = new Image(f.toURI().toString());
Integer ilosc = 0;
for (int i = 0; i<=Ilosc;i++)
{
for(int k = 1;k<Scena.getColumnConstraints().size();k=k+2)
{
if(k%2 != 0)
{
Circle circle = new Circle(20, 20, 20);
circle.setFill(new ImagePattern(image));
Scena.add(circle,k,i);
list.add(new Krawendzie(ilosc,ilosc));
ilosc++;
}
if(ilosc == Ilosc)
break;
}
if(ilosc == Ilosc)
break;
}
getData();
}
public void getData()
{
ObservableList<Krawendzie> obsList = FXCollections.observableArrayList(list);
laczenie.setItems(obsList);
//return obsList;
}
}
And Main Application
public class JavaFXApplication4 extends Application {
#Override
public void start(Stage stage) throws Exception {
Parent root = FXMLLoader.load(getClass().getResource("FXMLDocument.fxml"));
Scene scene = new Scene(root);
stage.setScene(scene);
stage.show();
}
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}
}
