Javascript Question

Why is my ng-model variable undefined in controller?

I'm having trouble with $scope in my angular js project. When I use ng-model="modelExample" on an input field for example, I can't access it in my js using $scope.modelExample. Has anyone else had a similar problem?

It's bizarre, a function is called but ng-model doesn't bind. See my code below, the function refreshResults() is called when I submit the form but $ returns as undefined.

// 'ui.bootstrap',

.config(function($stateProvider, $urlRouterProvider) {
.state('app', {
url: "/app",
abstract: true,
templateUrl: "templates/menu.html",
controller: 'AppCtrl'

.state('app.browse', {
url: "/browse",
views: {
'menuContent' :{
templateUrl: "templates/browse.html",
controller: 'BrowseCtrl'

.state('', {
url: "/search",
views: {
'menuContent' :{
templateUrl: "templates/search.html",
controller: 'SearchCtrl'
// if none of the above states are matched, use this as the fallback

angular.module('starter.controllers', [])
.controller('SearchCtrl', function($scope) {
$scope.refreshResults = function() {

<ion-content class="has-header">
<form ng-submit="refreshResults()" class="bar bar-header item-input-inset">
<label class="item-input-wrapper">
<i class="icon ion-ios7-search placeholder-icon"></i>
<input type="search" placeholder="Search..." ng-model="search">


@DavidTryon solved my issue in the comments. I was using scope wrong. I needed to use an object not a string. In other words I need to do something like ng-model="search.term" not ng-model="search" and use it in the js like this: $ It has to do with inheritance but long story short, if your ng-model doesn't have a dot (.) in it, you're doing it wrong.

Here's more info:

Thanks David!
