I've had to change some of the code to make it work with the new versions of Ladda and AngularJS

The buttons look like this now:

    <button id="w" type="submit" class="ladda-button" data-color="blue" data-style="zoom-in" ladda="loading">
      <span class="ladda-label">Submit</span>
    </button>

(The text needs to be wrapped inside a span.ladda-label, the value of the ladda attribute is the value on the scope that is being watched.)

The directive looks like this:

    app.directive('ladda', function(){
        return {
            restrict: 'A',
            link : function(scope, element, attrs){
                var l = Ladda.create( document.querySelector('#'+attrs.id));
                scope.$watch(attrs.ladda, function(newVal, oldVal){
                    if (newVal !== undefined){
                        if(newVal) {
                            l.start();
                        }
                        else {
                            l.stop();
                        }
                    }
                });
            }
        };
    });

I modified the code in order to use it within a ngRepeat loop. With this version, there is no need to specify an id for each button. The element is enough.

app.directive('ladda', function() {
    return {
      restrict: 'A',
      link: function(scope, element, attrs) {
        if (element && element[0]) {
          var l = Ladda.create(element[0]);
          scope.$watch(attrs.ladda, function(newVal, oldVal) {
            if (newVal !== undefined) {
              if (newVal)
                l.start();
              else
                l.stop();            
            }
          });
        }
      }
    };
  });

@ValentinH - nice modification! much better than the previous reliance on the ID
