Jestem nowy w ember Próbuję dołączyć szablon do innego i wydaje się, że działa, ale wywołuje błąd, czy możesz wyjaśnić dlaczego?

Błąd:

Assertion failed: You cannot append to an existing Ember.View. Consider using Ember.ContainerView instead

To jest kod wapp.js

App.NewStickie = Ember.View.extend({
  click: function(evt){
    var stickie = Ember.View.create({
        templateName: 'stickie',
        content: 'write your notes here'
    });
    stickie.appendTo('#stickies');
  }
});

Oto zawartośćindex.html

<script type="text/x-handlebars">
    {{#view App.NewStickie}}
      <button type="button" class="btn btn-success">
        New
      </button>
    {{/view}}
    {{outlet}}
