Rails - refresh/render question after select box onchange event

Hi there,

I have a paginated list, and a select box of numbers showing how many pages to display. When the user picks a value I want the screen to refresh with the resized list.

View:

<%= select_tag :paginate_size, options_for_select([['Display: 5', 5],['Display: 10',10],['Display: 20', 20],['Display: 30', 30],['Display: 50', 50],['Display: 100',100]]), :onchange => remote_function(:url => {:action => :show_my_entries}, :with =>"'paginate_size='+value")%>

When I select a value I can see in the log that the show_my_entries function is being called and sent the paginate_size parameter.

In the controller I set the per_page variable as shown below, however selecting anything in the list doesn't refresh the screen with the new list size:

def show_my_entries
 if (params[:paginate_size].nil?)
      paginate_size = 8
    else
      paginate_size = params[:paginate_size]
    end

    @entries = Entry.find_all_my_entries_by_pub(session[:publication_id], session[:user_id])

    @entries_paginate = Entry.paginate :page => params[:page], :order => 'title', :per_page => paginate_size,
          :conditions => "publication_id = " + session[:publication_id].to_s + " AND writer_id = " + session[:user_id].to_s

    render :layout => "dashboard"

  end
