Thank you "ajpiano" for advising me respectfully
And also you "sindresorhus", Thank you for consulting
However I think closing of that bug was not attentively because I told "live / delegate" not exactly "live"(as a deprecated method) so obviously the actual problem is probably in another point or core
Actually that bug took a lot of my time to find the sub-bugs and finally I decided to let other friends to know that.
I have no problem with "Mr. Dave Methvin" but if jQuery is a free opensource js+dom library it doesn't mean caring customers is not important. I came to help but I had to spend a lot of time on jsFiddle and on jQuery Bug Tracker and finally I saw my post was "CLOSED/INVALID BUG". I think it is not respectful.
So if jQuery has no time to spend for friendly bug reports I have no more time spend also. BYE
