Partial fix for nested child components updates bug

[gschurck]

Partial fix proposal for #530.

As I explained in the issue, the bug seems to be linked to the fact that script tags where not updated for each child components displayed after the first page load. Resulting in children being ignored and no actions could work on it.

With this fix, actions worked for me.
But to test it I had to set children components data field manually on client side according to their state on server, because I don't know how to get the data field efficiently for each new child. We need it to validate the checksum and send a request to the server.

Let's try to get this in a mergeable state 🙇‍♂️

@adamghill can you please elaborate on "how to get the data field efficiently for each new child"?

Yep, so what @gschurck is saying is this fix would require the code to look at every DOM element node on the page every time a new AJAX call is received. I need to test the performance implications of this and I'd also like to figure out if maybe there is a simpler and/or more straight-forward approach. I'll let you know what I come up with.

@imankulov this is a fundamental feature, please check with @adamghill

I think this should be fixed by 0.58.0 of Unicorn which drastically improves child components so I'm going to close this PR. If it is still a problem feel free to re-open a new issue. Thank you!
