I think there is a problem with adding callbacks for physics.group.  
Whenever I do this

```
enemyGroup = this.physics.add.group({
        defaultKey: 'enemy',
        maxSize: 5,
        createCallback: function(enemy){
            enemy.setData('health',3);
            console.log(enemy.getData(health));
        },
    });

```

the callback doesnt trigger but when i change `this.physics.add.group` to `this.add.group` the callback fires. Is this a bug on Phaser 3? if so is there a work around?

Physics use their own createCallback internally, and ignore any passed in the config.

But you can override it. See
