JavaFX: ImageView on setOnDragDropped not triggering

I am using SceneBuilder to develop a JavaFX application. I have ImageView object and setOnDragDropped is not triggering. I am not getting any errors. For onDragDetected everything is working. I tried these two options: 1) to set it from the SceneBuilder (see the screenshot) enter image description here

Second way was from the controller code:

@FXML public void sensorDrop(DragEvent  event) {
    System.out.println("Drooooop!>>");
    event.consume();
    //TODO More useful code
 }

Any thoughts?

To make it complete- in order to register it the setOnDragOver has to be registered

label.setOnDragOver(new EventHandler <DragEvent>() {

    public void handle(DragEvent event) {
        event.acceptTransferModes(TransferMode.ANY);
        event.consume();
    }
});

I took this answer from: JavaFX OnDragDropped Not Registering

The onDragDropped handler is called when you drop something onto the node with which it is registered, not when you drop that node on something. So you need to register the onDragDropped handler on the stack pane.
