javascript - クラス/IDによって追加された要素からタグを削除する

Question

次のコードがあり、ユーザーが何か他のものを編集するために移動したときに、以前に追加されたテキスト「You are nowediting this」を DOM から削除できません。アドバイスをいただければ幸いです。jQLiteで実現できると思うので、jQueryも使用しないようにしています。どうもありがとう。

var editApp = angular.module('editApp', ['ngRoute']);

editApp.directive('editInPlace', function() {
  return {
    restrict: 'EA',
    scope: {
      value: '=editInPlace'
    },
    template: '<span ng-click="edit()" ng-bind="value"></span><input ng-model="value"></input>',
    link: function($scope, element, attrs) {
      // Let's get a reference to the input element, as we'll want to reference it.
      var inputElement = angular.element(element.children()[1]);

      // This directive should have a set class so we can style it.
      element.addClass('edit-in-place');

      // Initially, we're not editing.
      $scope.editing = false;

      // ng-click handler to activate edit-in-place
      $scope.edit = function() {
        $scope.editing = true;

        // We control display through a class on the directive itself. See the CSS.
        element.addClass('active');
        element.append('<b class="yaet">You are now editing this</b>');
        // And we must focus the element. 
        // `angular.element()` provides a chainable array, like jQuery so to access a native DOM function, 
        // we have to reference the first element in the array.
        inputElement[0].focus();
      };

      // When we leave the input, we're done editing.
      inputElement.prop('onblur', function() {
        $scope.editing = false;
        element.removeClass('active');
        element.remove('.yaet'); // This is bit that fails
      });
    }
  };
});

editApp.controller('ContactsCtrl', function($scope) {
  $scope.contacts = [{
    number: '+25480989333',
    name: 'sharon'
  }, {
    number: '+42079872232',
    name: 'steve'
  }];
});

.edit-in-place span {
  cursor: pointer;
}
.edit-in-place input {
  display: none;
}
.edit-in-place.active span {
  display: none;
}
.edit-in-place.active input {
  display: inline-block;
}
