i have a dynamic list, which looks like this:
- Text1
- Text2<
I think you are not showing us some part of your code as i suspect you are trying to generate that id dynamically, meaning u set it dynamically as well. you have to make sure that there is no 'space' character within the id which will likely mess thing up...
$('#tl_2').remove();
Works according to jquery documentation. it worked for me.
