If I change the value of the TinyMCE tag,the content has no change.

Because in TinyMCE.js the render method use defaultValue for the content. So my solution is add this function to the TinyMCE class:

componentDidUpdate: function componentDidUpdate(prevProps, prevState) {
    if(prevProps.content!==this.props.content){
        tinymce.EditorManager.get(this.id).setContent(this.props.content);
    }
  }

yes please!
