[jQuery] click event is not working

[jQuery] click event is not working

hi,
i'm appending a child div in a parent div. parent div has already
child div's which have classes ws_c1 and plus.
$
'<div></div>'
.addClass
'ws_c1'
.addClass
'plus'
.appendTo
$
'#'
'parentdiv'
counter
;
but when i try to do this
$
".ws_c1.plus"
.click
function
{alert
'test'
;}
;
It works on other child div's but not on the appended div's. I've also
tried with Id's.
can you plz help me.
regards,
