You shouldn't do this back and forwarding with rjs. You're returning javascript to be executed by the client, and you can't get the value back directly unless you embed another AJAX call into the javascript your return.

A better way to do this would be to use a single AJAX call. Use a remote_form_for with a text_field for the user to enter their name into, then POST it to your controller action and store it in the database in the normal fashion.

Something like:

# In your view
<% remote_form_for :user, :url => { :controller => :users, :action => :create } do |f| %>
  <%= f.text_field :name %>
  <%= f.submit %>
<% end %>

# In your controller
def create
  @user = User.new(params[:user])
  @user.save
  render :update do |page|
    # Return whatever javascript you want here
    page << "alert('Created user')"
  end
end
