Soft Rejection : I need help with main javascript file

Hello Everyone,

I got a soft rejection today,

the reviewer said the following :

PROPER EVENT BINDING: Consider using the preferred .on() method rather than .click(), .bind(), .hover(), .load(), .ready(), etc. For best performance and concise code use event delegation whenever possible: https://codepen.io/32bitkid/post/understanding-delegated-javascript-events

Despite checking over and over I didn’t find where is the issue exactly :

I’m pasting the code of my Javascript main file, I will be very grateful if anyone could give me a few minutes from his time to check it.
