only able to update email but fname etc not updating

I am using Restful_Authentication plugin for login/logout. I am trying to update the profile page which has columns email and fname etc, its updating only the email column but not updating the fname and other columns once i hit save and gives me flash message as 'Profile was successfully updated. Please let me know how can i fix it to update all fields not just email field.

-- following is the code in my users_controller.rb :-

class UsersController < ApplicationController   # render new.rhtml   def new     @title = 'new'   end

def create     cookies.delete :auth_token     # protects against session fixation attacks, wreaks havoc with     # request forgery protection.     # uncomment at your own risk     # reset_session     @user = User.new(params[:user])     @user.save     if @user.errors.empty?       self.current_user = @user       redirect_back_or_default('/session/new')       flash[:notice] = "Thanks for signing up!"     else       render :action => 'new'     end   end

  def update     @user = User.find(params[:id])

    respond_to do |format|       if @user.update_attributes(params[:user])         flash[:notice] = 'Profile was successfully updated.'         format.html { redirect_to :controller => 'sessions', :action => 'edit_profile' }         format.xml { head :ok }       else         flash[:error] = 'Unable to update profile.'         format.html { render :controller => 'sessions', :action => 'edit_profile' }         format.xml { render :xml => @user.errors, :status => :unprocessable_entity }       end     end   end

  def edit     @user = User.find(params[:id])   end

end

-- following is the code in my edit_profile.html.erb file located in (views/sessions/edit_profile):-

<h2> Edit Profile </h2> <% form_for @current_user do |f| %> <%= f.error_messages %>

  <p>     <%= f.label :email %><br />     <%= f.text_field :email %>   </p>   <p>     <%= f.label :fname %><br />     <%= f.text_field :fname %>   </p>   <p>     <%= f.label :middle_name %><br />     <%= f.text_field :mname %>   </p>   <p>     <%= f.label :last_name %><br />     <%= f.text_field :lname %>   </p>   <p>     <%= f.submit "Save" %>   </p> <% end %>
