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
@ValentinH - This is perfect. A gold star for you, sir.

The directive looks like this:
