Adding new Fields to my Form

Adding new Fields to my Form

Hello!

I use jquery to add new rows in my table which is encased by a form.
I do things like: $('#weekTable tr:last').after("<tr><td><input name='kategorie"+i+"' type='text' value=''></td></tr>");

That works very good but when I post the form the new inputs aren't posted to the server because javascript doesn't chance the source... is there any solution to post also the new added inputs to the server?

Thank you and best regards,
