JQuery code no longer working after migrating from 2013 to 2016

Hi we have migrated from Nintex Forms 2013 to 2016 and our JQuery code read on repeating section no longer works.

Using below code we can iterate thru the controls from the repeating section

NWF$(".rptMain").find(".rptDetail").children(".nf-repeater-row:not('.nf-repeater-row-hidden')")

It is working on Nintex 2013.

Not working on Nintex 2016.
