How can I use Bootstrap Multiselect Dropdown in AngularJS

Question

I want to use Bootstrap Multiselect Dropdown http://davidstutz.github.io/bootstrap-multiselect/ in AngularJS. I hear that it's necessary to move it to Directive. But I think it's quite complicated & don't know what I have to do. If you have experienced, please guide me! Tks.

Here is a directive I use in my project. It works on Chrome and Firefox. You can change the options based on your own need.

angular.module('yourApp')
.directive('yourDirective', function () {
    return {
        link: function (scope, element, attrs) {
            element.multiselect({
                buttonClass: 'btn',
                buttonWidth: 'auto',
                buttonContainer: '<div class="btn-group" />',
                maxHeight: false,
                buttonText: function(options) {
                    if (options.length == 0) {
                      return 'None selected <b class="caret"></b>';
                    }
                    else if (options.length > 3) {
                      return options.length + ' selected  <b class="caret"></b>';
                    }
                    else {
                      var selected = '';
                      options.each(function() {
                        selected += $(this).text() + ', ';
                      });
                      return selected.substr(0, selected.length -2) + ' <b class="caret"></b>';
                    }
                }
            });

            // Watch for any changes to the length of our select element
            scope.$watch(function () {
                return element[0].length;
            }, function () {
                element.multiselect('rebuild');
            });

            // Watch for any changes from outside the directive and refresh
            scope.$watch(attrs.ngModel, function () {
                element.multiselect('refresh');
            });

        }

    };
});

Update two snippets for the directive which working on AngularJS v1.3.15 and bootstrap-multiselect v0.9.6: JavaScript, CoffeeScript
