Why doesn't this jQuery script work on mobile devices?

Question

JavaScript

Hello, I have this jquery script:

<script>$('#deleteCartIphoneCategory').attr('data-item-delete', '1');</script>

Why doesn't it work on phones (chrome android), and for some reason it doesn't work on iPhone (safari)(
It works on desktop. Tried adding type="text/javascript" didn't help.

How can I fix this? Thanks in advance for your help. I will be very grateful
