Ember: How to valuebind TinyMCE textarea field to model

Question

I have a TinyMCE embedded in a template. Now, I want to valuebind the content of the TinyMCE editor (which is in fact a textarea).

See http://jsfiddle.net/cyclomarc/wtktK/10/

When entering text in the textfield, the text in the {{bodyText}} is updated. I would also like to update the text in the TinyMCE textarea ...

Any idea how to do this ?

HTML:

<script type="text/x-handlebars">
    <h2>Tiny MCE</h2>
    {{outlet}}
</script>

<script type="text/x-handlebars" data-template-name="index">
        <form method="post" action="somepage">
            App.IndexController.bodyText value:</br>
            {{bodyText}}
            </br></br>

            Bound to Ember.TextField:<br>
            {{view Ember.TextField valueBinding='bodyText'}}

            </br></br>
            Bound to Ember.TextArea:</br>
            {{view Ember.TextArea valueBinding='bodyText'}}

        </form>
</script>

JS:

var App = Ember.Application.create({
  LOG_TRANSITIONS: true
});

App.Router.map(function () {});

App.IndexRoute = Ember.Route.extend({ });

App.IndexController = Ember.Controller.extend({
    bodyText: '...' 
});

App.IndexView = Ember.View.extend({
    didInsertElement: function(){
        tinymce.init({
            selector: "textarea"
        });
    }
});

I made some changes in your fiddle.

Give a look here http://jsfiddle.net/Jw75L/26/

First I removed the var from App declaration, to become the App namespace global and visible in handlebars template.

And replaced the tinymce from IndexView to TinymceView, to be reusable.

App.TinymceView = Ember.TextArea.extend({
    editor: null,
    _suspendValueChange: false,
    didInsertElement: function(){
        var id = "#" + this.get("elementId");        
        var view = this;
        tinymce.init({
            selector: id,
            setup : function(ed) {                
                view.set("editor", ed);
                ed.on("keyup change", function() {
                    view.suspendValueChange(function() {
                        view.set("value", ed.getContent());
                    });
                });
           }
        });
    },
    suspendValueChange: function(cb) {
        this._suspendValueChange = true;
        cb();
        this._suspendValueChange = false;
    },
    valueChanged: function() {
        if (this._suspendValueChange) { return; }
        var content = this.get("value");
        this.get("editor").setContent(content);
    }.observes("value"),
    willClearRender: function() {        
        this.get("editor").remove();
    }
});

Because TinyMCE changes the textarea and create a lot of elements, I had that observer the change in the TinyMCE and propagate to the TinymceView, using ditor.on("keyup"....
