[html] Edit In Place Content Editing

I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.

The example is available here http://plnkr.co/edit/EsW7mV?p=preview

Here goes the code:

app.controller('MainCtrl', function($scope) {

  $scope.updateTodo = function(indx) {
    console.log(indx);
  };

  $scope.cancelEdit = function(value) {
    console.log('Canceled editing', value);
  };

  $scope.todos = [
    {id:123, title: 'Lord of the things'},
    {id:321, title: 'Hoovering heights'},
    {id:231, title: 'Watership brown'}
  ];
});

// On esc event
app.directive('onEsc', function() {
  return function(scope, elm, attr) {
    elm.bind('keydown', function(e) {
      if (e.keyCode === 27) {
        scope.$apply(attr.onEsc);
      }
    });
  };
});

// On enter event
app.directive('onEnter', function() {
  return function(scope, elm, attr) {
    elm.bind('keypress', function(e) {
      if (e.keyCode === 13) {
        scope.$apply(attr.onEnter);
      }
    });
  };
});

// Inline edit directive
app.directive('inlineEdit', function($timeout) {
  return {
    scope: {
      model: '=inlineEdit',
      handleSave: '&onSave',
      handleCancel: '&onCancel'
    },
    link: function(scope, elm, attr) {
      var previousValue;

      scope.edit = function() {
        scope.editMode = true;
        previousValue = scope.model;

        $timeout(function() {
          elm.find('input')[0].focus();
        }, 0, false);
      };
      scope.save = function() {
        scope.editMode = false;
        scope.handleSave({value: scope.model});
      };
      scope.cancel = function() {
        scope.editMode = false;
        scope.model = previousValue;
        scope.handleCancel({value: scope.model});
      };
    },
    templateUrl: 'inline-edit.html'
  };
});

Directive template:

<div>
  <input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
  <button ng-click="cancel()" ng-show="editMode">cancel</button>
  <button ng-click="save()" ng-show="editMode">save</button>
  <span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
    <span ng-hide="editMode" ng-click="edit()">{{model}}</span>
    <a ng-show="showEdit" ng-click="edit()">edit</a>
  </span>
</div>

To use it just add water:

<div ng-repeat="todo in todos" 
     inline-edit="todo.title" 
     on-save="updateTodo($index)" 
     on-cancel="cancelEdit(todo.title)"></div>

UPDATE:

Another option is to use the readymade Xeditable for AngularJS:
