Cannot load custom js with <script> on version 6.x

[CnBDM-Su]

I use IPython HTML to load custom js like
HTML(<script>custom js content</script>) works well in notebook on version 5.x and 7.x.
But fail in 6.x.

The IPython HTML cannot find it. when I call it, it shows xxx not defined in console.

Does anyone know how to solve this without change the version of notebook?
Is there specific load custom js approach for version 6.x?

Thanks

Hi @CnBDM-Su can you share which version of Notebook 6 you are experiencing this problem with?

@RRosio 6.4.0

Thank you for the update @CnBDM-Su, have you also used the display function from IPython.display? On my end, using Notebook 6.5.7 wrapping the HTML function call in a display() works as expected.
