Ajax pagination and RJS

Hi
I have view code like(The view is completely inside div
view_sd_attachment)
<%= will_paginate @sd_attachments, :remote => {
:url=>{:action=>‘sd_attachment_pagination’,:id=>@sd_ticket} }, :renderer
=> ‘RemoteLinkRenderer’ %>

And in action ‘sd_attachment_pagination’ the code as below

def sd_attachment_pagination

@sd_ticket=ServiceDeskTicket.find(params[:id])
@sd_attachments=@sd_ticket.service_desk_attachments.display_sd_attachments(params[:page])

end

And I wrote a corresoponding sd_attachment_pagination.rjs as
page[:view_sd_attachment].replace_html :partial =>
‘service_desk_part/view_sd_attachment_details’

But the div is not replaced.But the data is printed on background and
all.Why the div is not replaced

Thanks in advance
Sijo
