Delete added items

Delete added items

So, I'm trying to add new items to the list and delete them on "remove" click. The adding part is OK, but when I add items into my list, I cannot remove the added items by clicking "remove", but I can do this with the first three list items (since they are on the page already). Is there anyone that can help me solve this problem? I tried debugging using the console but it didn't help. Many thanks!
P/s: I'm new to jQuery.
