Link_to syntax with rails3 (link_to_remote) and basic javascript not working in rails3 application?

Question

I am wondering if the basic link_to syntax is completely broken in the current rails3 master server or if I am doing the wrong syntax here.

= link_to "name", nil, :onlick => "alert('Hello world!');"

should actually trigger a warning when pressed. very simple. not working on my rails3 project! (also no way out error!) any ideas?

for the general syntax of link_to, I could not find an example where I could combine link_to_remote with a confirmation, remote and html class (see my attempt below)

= link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich Löschen?" }, :class => "trash"

even rails3 api doesn't help me here: http://rails3api.s3.amazonaws.com/index.html

help!
