What happens to jQuery handlers when the HTML elements are removed?

Hi all, if I have installed some handlers, say click, focus, etc, and later, I remove the associated elements by doing .html("").

Now,

Q1: What happens to those handlers? Are they cleaned up automatically?

Q2: If Q1 is no, then if I recreate the elements with the same ID (or class that matches the original selector), would the old handlers still be associated with the elements?

I guess ultimately, what is the proper way of removing HTML elements? .remove() or .html("").

Thanks a lot!
