@vervoortyves Perhaps Giri is right.
I was trying to solve a similar issue here…

And could not get it to work properly.
@Yvervoort. I know what you mean, when you say, that you are able to create new HTML-Elements, but unfortunately it did not work at the end, due to some inteferences between the implemented and the onMessage-command.
Read the shown post, i think it has some similarity (not sure).
