Event KeyCode Jquery does not work

Good day, I have a problem when trying to program the KeyCode event. I'm sure it has nothing to do with the JQuery library because I already tested an alert, which tells me it's working fine.

I hope you can help me, I have reviewed the code several times but I have not been able to see the error.

I leave the fragment of the code where the input is and the part of js where the event is located.

Thanks in advance

The problem is that you have duplicated the attribute class in your input , then the second attribute class is ignored. You can check it by listing the items with class .menge with $('.menge') you will notice that nothing is returning.

Your input should look like this:

<input type="text" class="form-control text-center menge" value="<?php echo $daten[$i]['menge'];?>"
                                        data-preis="<?php echo "€" . number_format( $daten[$i]['preis'],2); ?>"
                                        data-id="<?php echo $daten[$i]['produkt_id']; ?>">

On the other hand, you have a badly closed tag, the form that starts inside the tbody , but ends outside the table and you also have a h4 within a p , which is incorrect .
