jquery - How do I add click events to a tinyMCE 4 file_picker_callback window? -

i'm trying add jquery click event listeners custom file browser window file_picker_callback i'm not having success.

i'm able add click events first popup window using:

setup : function(ed) {       ed.on('click', function(e) {           console.log('editor clicked');       });    } 

my first window insert/edit image window that's built tinymce 4.2 however, not desired target. desired target window launched when click file browser button pictured below. when invoke file_picker_callback, file browser icon (circled).

when click on file browser button, have second window appear i'll using file browser, this window want add events.

below code i'm using invoke file_picker_callback...

init:

tinymce.init({     //...     file_picker_callback: function (callback, value, meta) {         imagefilepicker(callback, value, meta);     } }); 

code second window:

var imagefilepicker = function (callback, value, meta) {     tinymce.activeeditor.windowmanager.open({         title: 'image picker',         url: '/images/getimages',         width: 900,         height: 550,         onpostrender: function () {             docrap();         },         buttons: [{             text: 'insert',             onclick: function () {                 tinymce.activeeditor.windowmanager.close();             }         }, {             text: 'close',             onclick: 'close'            }],         }, {             oninsert: function (url) {                 callback(url);                 alert("derp");            },         });    };
