<https://github.com/JetBrains/kotlin-wrappers/pull/565/files#diff-71d8431fc71894a3148c8b3b77a8d760b632ce0d374fd50f84bc39c2fbfcbc27L247> how can I access `ref` in `RBuilder` after this change?!

```ref = RefCallback&lt;dynamic&gt; {
  doSomethingWithRef(it)
}```

`useRefCallback` better :slightly_smiling_face:
Also strict type parameter recommended (automatic in future)

Hmm, `useRefCallback` requires `Element`, bu I don't have that. I'm trying to do this: <https://github.com/uiwjs/react-codemirror/blob/master/website/App.js#L190> (I already have my `external class CodeMirror`)

<https://github.com/JetBrains/kotlin-wrappers/pull/701|It’s not a problem> :slightly_smiling_face:

Also <https://github.com/JetBrains/kotlin-wrappers/pull/702|useRefState> will be available in next release
