I'm new to Angular JS.
I have a few questions. Scope seems to be working with my first controller testController but not with my second controller controlspicy.
Why is not letting me print out $scope.greeting ? Shouldn't the binding work because I assigned a controller.
Here's a plunkr link which directs straight to the code.

<!DOCTYPE html>
<html ng-app="newtest">
<head>
<script data-require="angular.js@*" data-semver="1.3.5" src="https://code.angularjs.org/1.3.5/angular.js"></script>
<link rel="stylesheet" href="style.css" />
<script src="script.js"></script>
<script src="spicy.js"></script>
</head>
<body ng-controller="testController">
<h1>Hello Plunker! {{message}}</h1>
<input type="text" name="firstName" ng-model="thetext">
{{double(thetext)}}
<h1 ng-controller="controlspicy">new test</h1>
<h2>{{greeting}}</h2>
</body>
</html>
script.js
var app = angular.module("newtest", [])
.controller("testController", ["$scope", function($scope) {
$scope.message = "hola";
$scope.double = function(value){
if (value == null){
return 0;
}
return value*2;
};
}]);
spicy.js
var appl = angular.module("thespicy", []) .controller("controlspicy", ["$scope", function($scope){
$scope.greeting = "hello";
}]);
As previously mentioned by Preston you need to wrap the <h2> inside a tag with ng-controller. There is one more issue however. controlspicy is defined in another module than the one you specify in ng-app. Change angular.module("thespicy", []) in spicy.js to angular.module("newtest").
You should almost never use more than one module in one app. You could however divide it into different sub-modules but if your new to Angular I would recommend using just one module to start with.
To clarify; you should only define a module once by typing angular.module("module_name", []). Notice the [] here. In this array you would put dependencies for the module (if you really wanted the 'thespicy' module you could have included it as a dependency with angular.module("newtest", ['thespicy']). If you later wanted to add a controller to the module you would reference the module with angular.module("module_name") (no []). For example:
// Define a module
angular.module('foo', []);
// Reference the previously defined module 'foo'
angular.module('foo')
.controller('barCtrl', function() { ... });
Here is a working fork of your example: http://plnkr.co/edit/rtUJGeD52ZoatoL3JgwY?p=preview btw.
