State persistence between child views and controllers

I have a Java FX application with has a main view (FXML) and its controller. I am trying to simulate a tabpane like child views(FXML) with their own controllers. So far so good, I am able to switch between the child views with the following code :

//page type para is the path of FXML file
private void changePage(String pageType) throws IOException
{
    childScene.getChildren().clear();
    FXMLLoader loader = new FXMLLoader(getClass().getResource(pageType));

    loader.setControllerFactory((Class<?> controllerClass) ->
    {
        //trying to load a single instance controller of the child
        if (controllerClass == EngTaiController.class)
        {
            eng2TaiController.setData(words, selectedFont);
            return eng2TaiController;
        }
        try
        {
            return controllerClass.newInstance();
        }catch (Exception ex)
        {
            throw new RuntimeException(ex);
        }
    });
    Parent page = loader.load();
    VBox.setVgrow(page, Priority.ALWAYS);
    //childScene is the container for childviews
    childScene.getChildren().add(page);
}

The problem is that it doesn't persist any user state, text in textboxes, selection in list view, loaded custom controls in child views when switched from one view to another.
