I not using directives in the same element of controller.

Hey, I had the same problem too. I managed to reproduce this with the example plunkr. I had to include the ng-intro-method attribute like so:

<div class="content" ng-intro-options="introOptions" ng-intro-autostart="true" ng-intro-method="CallMe" ng-intro-autorefresh="true">

My guess is that it might be something to do with scopes, because later on in angular-intro.js, when autoStartWatch got called, scope.ngIntroMethod as well as the other methods were all undefined. I'll try to fix it later if I have time, but for now specifying ng-intro-method seems to work.

This error is throw because the directive definition need =? for optional scope binding.
