How to call the handler on change?

Question

CMS

Add a slider to your shopify site. I added, it works, I can change its parameters from the admin panel. But now, when changing the parameters or the text of the slider, it is necessary to reinitialize it so that without pressing the Save button to see all the changes, otherwise now it disappears after the changes and only after I click on save does it appear. So this is how do I properly bind to the onLoad and onUnload events
I have the code to initialize the slider revolution
