Okay, so I added the button and it didn't work. I did debug it with onClick function and just print out in the console and that worked.

I also tried to make hidden input but that didn't work either

And I don't know about any Javascript files how is interacting with this site.

I also forgot to mention this delete method worked before ...

I got it to work. Thanks for the help!

This was happening because I have all of this inside of a table. I had to move the form inside tag (It was at the bottom of the table)

Thanks again for all the help and suggestion!
