Attributes updating problem

[lvarayut]

First of all, thanks for the great plugin. I'm trying to apply your plugin with my project for a few hours and having some problems which is when the ng-* attributes got updated inside a ng-click, your plugin always takes old values of the ng-* attributes. For example,

HTML:

   <div class="container-narrow" ng-controller="MyController"
     ng-intro-options="IntroOptions" ng-intro-method="CallMe"
     ng-intro-oncomplete="CompletedEvent" ng-intro-onexit="ExitEvent"
     ng-intro-onchange="ChangeEvent" ng-intro-onbeforechange="BeforeChangeEvent"
     ng-intro-autostart="false">
   <button class="btn btn-large btn-success" ng-click="foo();">Demo</button>

Controller:

  $scope.foo = function() {
    $scope.IntroOptions = {
      steps: [{
        element: document.querySelector('#step1'),
        intro: "This is the first tooltip."
      }, {
        element: document.querySelectorAll('#step2')[0],
        intro: "<strong>You</strong> can also <em>include</em> HTML",
        position: 'right'
      }],
      showStepNumbers: false,
      showBullets: false,
      exitOnOverlayClick: true,
      exitOnEsc: true,
      nextLabel: '<strong>NEXT!</strong>',
      prevLabel: '<span style="color:green">Previous</span>',
      skipLabel: 'Exit',
      doneLabel: 'Thanks'
    };
    $scope.CallMe(); // At this point, your scope.IntroOptions, inside the link function, will be undefined
  };

Please see this problem in action on this Plunkr.

IMHO, I think that you should apply a $watch in all these attributes, for example:

        link: function(scope, element, attrs) {
            scope.$watch('ngIntroOptions', function(old, new){
                if(old !== new)
                    scope.ngIntroOptions = new;
            });
        }

i know it's been a while you posted it.

but now we've changed how the directive works, and i don't think it's necessary do that change anymore.

because, now we're using a service to give freedom to developers so they change the behavior as they need, and you may update the intro injecting the ngintroService.

version: 3.1.1 #112,

but if find noticed something that could be improved, i'll be pleased to do it :)

i'll close this issue for the time being, if you still need help tell us, i'll answer Asap
