event on after bind update?

I am binding a datatable with a form. The form updates values when a new datatable row is selected. I need to run a function each time a different row is selected.

I am putting the function in onAfterSelect, but it runs a step too late and uses the value of the previous row rather than the newly selected one. It appears onAfterSelect occurs before the bind update. onBindRequest doesn’t seem like what I’m looking for. Anything I can use that fires after binded components complete syncing?

use onSelectChange event
