Hi!
Prepared sample of
codepan.
The problem is the following:
Add an element in the DOM with class
user-button
at the same time want to hang the handler
click on all the items
user-button
, not hung several handlers after each function call, I removed the handler
for the click each item and then add again, but something is not removed as I want.

ie every time I click on
+ the handler is still added to the previous items, do not understand how the DOM works.
Pliz explain!
PS well, or if you know another solution I would be glad to hear :)
