[jQuery] catch events after dynamic insert/json

i have:
$("a.delete").click(function() { alert("test") });
after i fetch some json data and append new html:
// on json load
$("div.items).append("<a href='#' class='delete'>test</a>");
click events on items inserted after json data is loaded are not
working, how can i tell jquery to inspect DOM again and attach actions
on new elements?
