Not Hiding/Responding. Quadruple checked my code... can't figure out where I'm going wrong.

  // Problem: Hints are shown even when form is valid
  // Soultion: Hide and show them at appropriate times
var $password = $("#password");
var $confirmPassword = $("#confirm_password");
  // Hide events
$("form span").hide();

function passwordEvent(){
    // Find out if password is valid
  if($password.val().length > 8) {
      // Hide hint if valid
    $password.next().hide();
  } else {
      // else show hint
    $password.next().show();
  }
}

function confirmPasswordEvent(){
     // Find out if password and confirmation match
  if($password.val() === $confirm_password.val()) {
     // Hide hint if match
    $confirmPassword.next().hide();
  } else{
     // else show hint
    $confirmPassword.next().show();
}

// When event happens on password input
$password.focus(passwordEvent).keyup(passwordEvent).focus(confirmPasswordEvent).keyup(confirmPasswordEvent);

// When event happens on confirmation input
$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent);
