sDom with additional div and not empty oLanguage.sUrl

Hi. sorry for bad and strange English.

I have

"sDom": '<"H"lf>rt<"F"ip><"toolBar">' 

When I set oLanguage sub-params in code

"sLengthMenu":   "_MENU_",

, div with class toolBar created just after footer, and when later i use

$(".toolBar").append($( "#toolBar" )) 

- all OK.
but if i use

"sUrl": "js/us.txt"

, div with class toolBar created just after footer, and div with id #toolBar created in other place
i.e.

$(".toolBar").append($( "#toolBar" ))

not working.
as i understood in moment of execution $(".toolBar").append($( "#toolBar" )) there are not exists div with class toolbar and imposible append #toolbar to nothing.
