jQuery Event Basics / Extending Events to New Page Elements code incorrect

[rhumborl]

// Now create a new button element with the alert class. This button
// was created after the click listeners were applied above, so it
// will not have the same click behavior as its peers
$( "button" ).addClass( "alert" ).appendTo( document.body );

This is a selector to access the existing buttons, not creating a new element. Code should pass HTML:

$( "<button>" ).addClass( "alert" ).appendTo( document.body );

Indeed. The example is totally broken because of that. Testcase: http://jsfiddle.net/3wu574u4/1/

I wil open a PR with a fix.

Update: opened #587
