See below a SSCCE that shows that the listener gets called - but the flag is set to added when moving columns. Note that you need to call next() before using the change or you will get an IllegalStateException. See the javadoc of ListChangeListener.Change for a simple canonical example.

import javafx.application.Application;
import javafx.collections.ListChangeListener;
import javafx.scene.Scene;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.stage.Stage;

public class TableTest extends Application {

  public static void main(String[] args) {
      launch(args);
  }

  @Override
  public void start(Stage stage) {
    final TableView tableView = new TableView();
    final TableColumn[] columns = {new TableColumn("1"), new TableColumn("2")};
    tableView.getColumns().setAll(columns);
    tableView.getColumns().addListener(new ListChangeListener() {
        public boolean suspended;

        @Override
        public void onChanged(Change change) {
            change.next();
            if (change.wasReplaced() && !suspended) {
                this.suspended = true;
                tableView.getColumns().setAll(columns);
                this.suspended = false;
            }
        }
    });
    stage.setScene(new Scene(tableView));
    stage.show();
  }
}
