How to call .change() event inside revealing module pattern? - Javascript

I want to get the id of the select element on change event. My .change() event is defined inside a private function. As I am learning design patterns in javascript, I have used Revealing Module Pattern to define my functions.

I tried out two examples which are almost same(change is only in HTML) but one works and other doesn't.

This code snippet works

This code snippet DOES NOT work

I can't figure out the reason why this is happening

Also please comment on the proper way/standard way to define events inside revealing pattern
