Service is terminated when click on TableView - javafx

Question

I have the following problem. When I press the Button, I execute a Service that parses an html page and puts the results in a table. When I click on the table, while the Service is running, the Service will be terminated.
Can someone help me with this problem?
Here is my controller class:
public class ProxySearchController implements Initializable {
private Scene scene;
#FXML
private Button btn_refresh;
#FXML
private TableView<ProxyResult> tbl_results;
#FXML
private ProgressBar pb_search;
#FXML
private TableColumn<ProxyResult, String> column_ip;
#FXML
private TableColumn<ProxyResult, Integer> column_port;
#FXML
private TableColumn<ProxyResult, Locale> column_locale;
#FXML
private TableColumn<ProxyResult, String> column_anonymity;
#FXML
private TableColumn<ProxyResult, Boolean> column_google;
#FXML
private TableColumn<ProxyResult, Boolean> column_https;
#FXML
private TableColumn<ProxyResult, String> column_lastchecked;
#FXML
private TableColumn<ProxyResult, Long> column_response;
private ObservableList<ProxyResult> data = FXCollections.observableArrayList();
/*

#Override
public void initialize(URL location, ResourceBundle resources) {
tbl_results.setItems(data);
tbl_results.getSelectionModel().setCellSelectionEnabled(true);
Clipboard clipboard = Clipboard.getSystemClipboard();
// add listner to your tableview selecteditemproperty
tbl_results.getSelectionModel().selectedItemProperty().addListener(new ChangeListener<ProxyResult>() {
#Override
public void changed(ObservableValue observable, ProxyResult oldValue, ProxyResult newValue) {
ObservableList<TablePosition> posList = tbl_results.getSelectionModel().getSelectedCells();
int old_r = -1;
StringBuilder clipboardString = new StringBuilder();
for (TablePosition p : posList) {
int r = p.getRow();
int c = p.getColumn();
Object cell = tbl_results.getColumns().get(c).getCellData(r);
if (cell == null)
cell = "";
if (old_r == r)
clipboardString.append('\t');
else if (old_r != -1)
clipboardString.append('\n');
clipboardString.append(cell);
old_r = r;
}
final ClipboardContent content = new ClipboardContent();
content.putString(clipboardString.toString());
Clipboard.getSystemClipboard().setContent(content);
}
});
column_ip.setCellValueFactory(new PropertyValueFactory<ProxyResult, String>("ip"));

searchWorker.setOnSucceeded(new EventHandler<WorkerStateEvent>() {
#Override
public void handle(WorkerStateEvent event) {

}
});
searchWorker.start();
}

this.scene = scene;
