Add data to a custom menu button in TinyMCE -

how can add or associate data custom menu button in tinymce? code goes this:

    tinymce.init({         selector: 'textarea',         toolbar: " example",         setup: function (ed) {                                             ed.addbutton('example', {                 type: 'menubutton',                 title: 'insert latest newsletter link',                 icon: false,                 text: 'insert latest newsletter link',                 menu: [{text: "insert link", onclick: function () {                     //this want retrieve data                     //i associated button                 } }]             });         } 

the solution using 'value' in menu object like:

editor.addbutton( 'gavickpro_tc_button', {     title: 'my test button',     type: 'menubutton',     icon: 'icon gavickpro-own-icon',     menu: [         {             text: 'menu item i',             value: 'text menu item i',             onclick: function() {                 editor.insertcontent(this.value());             }         }    ] });
