sDom injection and bServeSide processing

Hi,

I'm fighting with the problem injecting my own toolbar via sDom variable as explained in the documentation. My sDom string looks like:

"sDom": 'lT<"#rechnung_liste_toolbar">frtip',

And I can see the div element with the id rendered properly but if I want to access it via jQuery selector like this (code below datatables initialization):

$('#rechnung_liste_toolbar').html('<b>Toolbar</b>');

The new html content is not set. I used firebug to find the problem and figured out that when i set a breakpoint at the line above, the right content (<b>Toolbar</b) is set. So I guess the selector is triggered before the table is totally initialized or something like this. Does anyone of you have an idea?

thanks,
Max
