              {
                match: /(^|\s)@(\w*)$/,
                search: function(term, callback) {

                        return mention.toLowerCase().indexOf(term.toLowerCase()) === 0 ? mention : null;

            ]);

            $(textcomplete).on({
              'textComplete:select': function (e, value) {
                scope.$apply(function() {
                  scope.message = value
                })
              },
              'textComplete:show': function (e) {
                $(this).data('autocompleting', true);
              },
              'textComplete:hide': function (e) {
