Set Properties from UIX

Hi There!

I am trying to set a few properties from the user input (textbox).

No issue on the frontend. However, I tried the simplest approach which is by having the function abc() declared within the <script> tag and then it call the function with onClick() method in html. No success.

I know a few people have shared a little bit of code snippet on updating workflow and whatnot.

Anyone can share the entry point for it? Because I kept getting 'Unable to get property ShellUI of undefined or null reference' error.

can calling the function with the onClick() html work?
