JavaScript jQuery Basics (2014) Creating a Password Confirmation Form Perfect

I don't know why this isn't working right

Something isn't working right with my code and I can't figure it out. As far as I can see, my code looks like it is right. However, when I was at the part in the video where I check my developers tools, it was showing canSubmit(); what I got was this instead of "false":

function canSubmit() {
Return isPassword Valid() && arePasswordsMatching();

Even when I made the change from "canSubmit();" to "enableSubmitEvent();" and refreshed the page, it didn't go away in the console part of the developer tools like it did for Andrew in the video. Plus, I never saw the 405 warning at any point when I ran the program in Workspaces. Any help on this is greatly appreciated. Here is my code:

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

//Hide hints
$("form span").hide();

function isPasswordValid() {
    return $password.val().length > 8;
}

function arePasswordsMatching() {
    return $password.val() === $confirmPassword.val();
}

function canSubmit() {
    return isPasswordValid() && arePasswordsMatching();
}

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

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

function enableSubmitEvent() {
    $("#submit").prop("disabled", !canSubmit());
}

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

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

enableSubmitEvent();

It sounds like you just named canSubmt (no parentheses) instead of invoking it: canSubmit().

Once I did what you suggested, that did work, But, it still isn't working the way it should. I typed in everything else in the developer tools as the video instructed and the this is what I ended up with:

$("#shift")
[<input type="submit" value="SUBMIT" id="submit" disabled>]
$("#shift").prop("disabled", true)
[<input type="submit" value="SUBMIT" id="submit" disabled>]

This happens even when I refresh the page after changing "canSubmit();" to "enableSubmitEvent();. I don't know why it it is doing this. All of that stuff should have disappeared when I refreshed the page. Did I leave something out to cause this to happen?
