<@U3DE1TXKP> maybe as dynamic, then: 
```
    val body = document.querySelector("body").asDynamic()
    body.foo = Foo(42)
    println(body.foo)
```

Man, today seems to be a bad day of for my examples. I actually wanted to write `document.getElementById('a').asDynamic().test = 12`.
That works well, that's what I currently do but its seems wrong to do it outside of the `div`.
The problem is, that the element does not yet exist (as far as I saw) at the point of
```
div('a') {
//here I need somehow access to the underlying div-instance
}
```
If i can get hold on the div-HTMLElement instance inside the `div` then I could work with asDynamic. Do you know a way to get the element?

You can try
```
div('a') {
    this.asDynamic().test = 42
}
```

unfortunately not `this` refers to the receiver of the `div` function, so to a DIV instance and not the div element

Ahhh yes, I had forgotten how it works. The builder is a complete abstraction with no access to the underlying DOM elements. So I you should store the reference outside of the DOM and just keep an id in the DOM using a special attribute.
