Ruby on Rails page does not refresh when form is p

Question

In the code sample posted below, I am trying to allow the user of the page to filter out which projects should be displayed by user. I am able to successfully filter the results by manually modifying the parameters passed in the address bar. But when I click the Filter button on the page it does nothing at all. It should refresh the page with the new parameters being passed when the button is pressed. Any ideas as to why this happens? Do I need to add anything in my controller?

View:

= form_tag projects_path, :method => :get do
  Include:
- @all_users.each do |user|
  = user
  = check_box_tag "users[#{user}]", 1, @all_users.include?(user), :id => "users_#{user}"
= submit_tag 'Filter', {:id => "users_submit"}

Console After Loading Main Page:

After clicking the submit button, nothing happens in the console, or does the browser seem to do anything. Rails 3.2.14 Ubuntu 12.04 LTS

Code was fixed with proper indentation:

= form_tag movies_path, :id => "ratings_form", :method => :get do
  Include: 
  - @all_ratings.each do |rating|
    = rating
    = check_box_tag "ratings[#{rating}]", 1, @ratings.include?(rating), :id => "ratings_#{rating}"
  = submit_tag "Refresh", :id => "ratings_submit"
