JQuery :: Append() And Remove() In Internet Explorer?

I come across one thing I havent found a workaround for yet:Im using append() to add a text line after loading the page:

$( element ).find( "p" ).append('<p2>' + eventName + '</p2>');

Later I want to remove the <p2> again. For all Browser this works fine (including Internet Explorer 9 beta) but not for any older version of IE:

$( element).find( "p2" ).remove();

I also tried empty() and detach() but with the same result .
