Why the ticker is not redrawing the stage?

import { utils, Application, Graphics } from 'pixi.js'
import { PixiConfig } from './constants'

const kind = utils.isWebGLSupported() ? 'WebGL' : 'canvas'
utils.sayHello(kind)

const state = {
	circle: { x: 0, y: 0}
}

const stage = () => {
	const graphics = new Graphics()

	graphics.lineStyle(0)
	graphics.beginFill(0xFFFF0B, .5)
	graphics.drawCircle(state.circle.x,90,60)
	graphics.endFill()

	return graphics
}

const gameLoop = delta => {
	state.circle.x += 1 + delta
}

const setup = () => {
	const app = new Application(PixiConfig)
	document.body.appendChild(app.view)

	app.stage.addChild(stage())
	app.ticker.add(delta => gameLoop(delta))
}

setup()

Hi,

I recently started to learn PIXI and now Im playing with animations using the ticker.

This code actually draws a circle and I can se gameLoop() is being called and updating state.circle.x though it looks like it not redrawing the stage.

What Im missing?
