Why can't I select a checkbox in my tableview?

I have a javaFX 8 pane that contains a Piles TableView. When I select a Pile from the TableView, it queries a database and populates a second TableView with instances of LogExt. This second TableView includes a column of checkboxes mapped to the LogExt.selected boolean property.

When I run the application, I can't select any of the checkboxes.

LogExt:

public class LogExt {
    private BooleanProperty selected = new SimpleBooleanProperty();
    private Log log;

    public LogExt(Log log) {
        this.setSelected(false);
        this.log = log;
    }

    public boolean isSelected() {
        return selected.get();
    }

    public BooleanProperty selectedProperty() {
        return selected;
    }

    public void setSelected(boolean selected) {
        this.selected.set(selected);
    }

    public Log getLog() {
        return log;
    }

    public void setLog(Log log) {
        this.log = log;
    }
}

The controller:

public class CustomOrderController {
    @FXML
    private RadioButton openRadio;
    @FXML
    private ToggleGroup stageGroup;
