what about the performance issue pointed out my @andreister ?

@rubo77 negligible at best. We're taking single-figure milliseconds.

@RoryMcCrossan that's a big deal for me though - I am looking for this because i have up to 3000 questions on a page that need events. One milisec each makes my page take 3 seconds longer to perform. Your comment isn't helpful for big lists.

The bigger issue is why you have 3000 questions on a page. If you follow good UI patterns you should never have that much information on a page. Look into paging, or lazy loading. Even using event delegation to have a single event handler for all those elements would be better.

@rubo77 - The performance gain is only seen when using event delegation by passing a selector parameter. If you call .on() without a selector parameter there is no performance improvement over using .click().
