I googled "angular directive trigger ng-change" and this StackOverflow question was the closest I got to anything useful, so I'll answer "How to trigger ng-change in a directive", since others are bound to land on this page, and I don't know how else to provide this information.

Inside the link function on the directive, this will trigger the ng-change function on your element:

element.controller('ngModel').$viewChangeListeners[0]();

element.trigger("change") and element.trigger("input") did not work for me, neither did anything else I could find online.

As an example, triggering the ng-change on blur:

wpModule.directive('triggerChangeOnBlur', function () {
    return {
        restrict: 'A',
        link: function (scope, element, attrs) {
            element.on('blur', function () {
                element.controller('ngModel').$viewChangeListeners[0]();
            });
        }
    };
}]);

I'm sorry that this is not directly answering OP's question. I will be more than happy to take some sound advice on where and how to share this information.
