Multi overlay touch

Hello! I have UI scene, and that ui scene has sprite with width = scene.width, and height = scene.height, so this sprite take all screen. I need this sprite for joystick, when i touch at that, joystick appear on place of my touch. But i have a problem : i need to handle touches from game screen and also from ui scene. So when i touch game screen sprite(pointerdown) i need to have touch event, and I need also when i move my finger on the area of another sprite or in empty area to joystick appear. How can I do that? thank you!

Solved! I use this.input.on instead sprite, and it is works.
