clicking save and nothing is happening...

When I click save the console.log statement does not show in the console. Ive checked the code 15 times, Im sure I'm looking over something but, help would be appreciated.

Index.html

<!doctype html>
<html lang="en">
<head>
  <title></title>
  <link href='https://fonts.googleapis.com/css?family=Varela+Round' rel='stylesheet' type='text/css'>
  <link href='styles/main.css' rel='stylesheet' type="text/css">
</head>
<body ng-app="todoListApp">
  <h1>My Todos</h1>
  <div ng-controller="mainCtrl" class="list">
    <input type="checkbox"/>
    <label class="editing-label">A sample</label>
    <input class="editing-label" type="text">
    </div>

  <div class="actions">
    <a href="">edit</a>
    <a href="" ng-click="helloWorld()">save</a>
    <a href="" class="delete">delete</a>
  </div>
  <script src="vendor/angular.js" type="text/javascript"></script>
  <script src="scripts/app.js" type="text/javascript"></script>
</body>
</html>

Javascript Code from my app.js

angular.module("todoListApp", [])
.controller('mainCtrl', function($scope){
  $scope.helloWorld=function(){
    console.log('Hello there this is the hello world controller function in the mainCtrl');
  };
});

Your div.actions needs to be inside of your div.list. Your div.list has the controller with the function helloWorld(). As div.actions is not inside div.list, it cannot access the functions in the controller. 

<div ng-controller="mainCtrl" class="list">
  <input ... />
  <label>...</label>
  <input ... />
  <div class="actions">
    <a href="">edit</a>
    <a href="" ng-click="helloWorld()">save</a>
    <a href="" class="delete">delete</a>
  </div>
</div>

Actually, what happened was that in the first video, Huston puts the new div for actions outside the div for class list. In the second video, they are where they should be, which is inside the div for list.

You did it exactly the way it was demonstrated, from one video to the next.

Hi Aaron,

Think about the explanation about $scope and check whether your actions div is within scope. Feels like our instructor gives us a first test of our understanding this way ;-)

Best, Bobby

wow I had this exact same problem. I was driving myself crazy. Who knew it was as simple as a div tag being closed in the wrong place.

Thank you for this answer! I was going crazy trying to find my error. I feel like I should start making a list of common errors to check through when my code isn't working :)
