Как реализовать группу ввода в xeditable встроенной форме?

    angular.module('xeditable').directive('editableInputGroup', ['editableDirectiveFactory',
      function(editableDirectiveFactory) {
        return editableDirectiveFactory({
          directiveName: 'editableInputGroup',
          inputTpl: '<div class="form-inline" style="width: 250px"><div class="input-group"><span class="input-group-addon" id="basic-addon1">#</span><input type="text"  class="form-control" placeholder="Name"  ng-model="$data" aria-describedby="basic-addon1" ></div></div>'
        });
    }]);

    (function() {
      var app;
      app = angular.module('app', ['xeditable']);
      app.run(function(editableOptions) {
        return editableOptions.theme = 'bs3';
      });
      app.controller('Ctrl', function($scope, $filter) {
        return $scope.user = {
          name: 'fun'
        };
      });
    }.call(this));
