Read Only binding

[bindrid]

I wanted to be able to tie the readonly status from the view model of the editor window. I finally settled on doing:

Before these lines

     // Get custom configuration object from the 'wysiwygConfig' binding, more settings here... http://www.tinymce.com/wiki.php/Configuration
var options = allBindings.has( 'wysiwygConfig' ) ? allBindings.get( 'wysiwygConfig' ) : null,
    // Get any extensions that have been enabled for this instance.
ext = allBindings.has( 'wysiwygExtensions' ) ? allBindings.get( 'wysiwygExtensions' ) : [],
     settings = configure( binding['defaults'], ext, options, arguments ); 

I added this:

		 binding['defaults'].setup =  function (editor) {
		    editor.on('init', function (e) {
		        if (allBindings.has('tinyMCEReadOnly')) {
                    // Set read only mode on init.
		            editor.setMode(allBindings.get('tinyMCEReadOnly')() ? 'readonly' : '');

                    // now subscribe to watch for more changes
		            allBindings.get('tinyMCEReadOnly').subscribe(function (isReadOnly) {
		                if (isReadOnly === true) {
		                    editor.setMode('readonly');
		                }
		                else {
		                    editor.setMode('');
		                }
		            });
		        }
		    });
		 }

and now my markup:

 <textarea id="divNoticeBody" readonly  data-bind="tinyMCEBinder: NoticeBody, tinyMCEReadOnly: NoticeReadOnly"></textarea>
