i'm implementing function where, when button clicked, text of button changed works properly. button appears when condition true works perfectly. when button appears when condition true when it's clicked values doesn't change.

 <button ng-if ="item.user == 'login'" class="{{love_default}}" ng-click=" love=!love">{{lovetext}}</button>

js

$scope.love = true; $scope.love_default = "button button-small button-positive icon icon-left ion-ios-heart"; $scope.$watch('love', function() {     $scope.lovetext = $scope.love ? 'login' : 'already logged in'; })
