Fire callbacks after updating layout in a callback

Hello Team,

I have a dashboard with a dropdown as the initial UI where a user can select the table name. I have a callback which captures the table name selected by the user and updates the layout based on selected table in the callback. Now I need to fire the callbacks for new layout which is generated.

Please let me know how can I achieve this since I don’t know the data before hand as I would do if I’m using a csv or flat files.
