    <p>In you case, I think you definitely should create a directive to encapsulate the button with its behavior. Here's an example:</p> <p><strong>HTML</strong></p> <pre><code>&lt;div ng-app='app'&gt; &lt;form id="id_request" ng-controller="RequestCtrl"&gt; &lt;input id="id_title" name="title" ng-model="request.title" type="text" class="ng-valid ng-dirty" /&gt; &lt;my-button state="state" click-fn="submitRequest()"&gt;&lt;/my-button&gt; &lt;/form&gt; &lt;/div&gt; </code></pre> <p><strong>Javascript</strong></p> <pre><code>angular.module('app', []) .directive('myButton', function() { return { restrict: 'E', scope: { state: '=', clickFn: '&amp;' }, template: '&lt;button type="submit" class="btn btn-primary" ng-click="clickFn()" ng-disabled="disabled"&gt;' + ' &lt;i ng-class="cssClass"&gt;&lt;/i&gt;' + ' {{ text }}' + '&lt;/button&gt;', controller: function($scope) { $scope.$watch('state', function(newValue) { $scope.disabled = newValue !== 1; switch (newValue) { case 1: $scope.text = 'Submit'; $scope.cssClass = ''; break; case 2: $scope.text = 'Submitting'; $scope.cssClass = 'icon-refresh icon-spin'; break; case 3: $scope.text = 'Error'; $scope.cssClass = 'icon-warning-sign'; break; case 4: $scope.text = 'Success'; $scope.cssClass = 'icon-ok'; break; } }); } }; }) .controller('RequestCtrl', function ($scope, $http, $timeout) { $scope.state = 1; $scope.request = {}; $scope.submitRequest = function() { $scope.state = 2; $http({ method : 'GET', url : '/ravishi/urSDM/3/', data : $.param($scope.request), headers : { 'Content-Type' : 'application/x-www-form-urlencoded', } }). success(function(data, status, headers, config) { $scope.state = 4; $timeout(function() { $scope.state = 1; }, 1500); console.log("success"); }). error(function(data, status, headers, config) { $scope.state = 3; $timeout(function() { $scope.state = 1 }, 1500); console.log("error"); }); } }); </code></pre> <p>jsFiddle <a href="http://jsfiddle.net/urSDM/12/" rel="nofollow">here</a>.</p>
