JS UNDO DOM modification

Is it possible to undo last DOM modification? I've tried to remember state after any change by undoArray = [ $("#container").clone() ]; //some situation when dom changed and remember state undoArray.push( $('#container').clone() ); And then, if needed, to restore `#container` content from this array, but it was loosing all events attached directly to elements.
If the only problem is event handling of dynamically generated elements, event delegation is the answer.
