jquery ajax return nothing

I'm using ruby on rails + jquery ajax

My function is for user check availability for new user registration.

function checkavailablity(){
    var username = jQuery("#user_email").val();
    var allNodes = 'name=' + username;
    var capture;

    if ((username).length > 0) {

        jQuery('#availability').show().text("Checking...");
        jQuery.ajax({
            url: "/user_available",
            data: allNodes,
            success: function(result) {
                // Call this function on success
        alert(result);
//            showResponseRegisterCheck( result );
//            return result;
        },
        error: function() {
            alert('Error occured');
        }

        });
    } else {
        jQuery('#availability').addClass('show_msg');
        jQuery('#availability').show().text('Please enter a valid email id');
        return false;
    }   
}

===========================================================================

and on rails my method is

def user_available
    render :nothing => true
    p user_email = params[:name]
    p @user_email = User.where("email = ?",user_email).first
    if @user_email.nil?
      @ww = "yes"
    else
      @ww = "no"
    end
    return @ww

  end

=====================================================================

my problem is
In my ajax-sucess I got no output but
in my rails method I'm returning yes or no value.

How about changes like followings.

- render :nothing => true
- return @ww
+ render :text => @ww  #at the last line
