During it's lifetime, the Dialog will notify all interesting events to the caller, provided he supplies a suitable callback in the contructor:

self.options.callback(event_name, dialog, params)

Example:

dialog1 = new Dialog({
    ...
    callback: function(event_name, dialog, params) {
        console.log('event_name: %o, dialog: %o, params: %o', event_name, dialog, params);
    }
});

Result:

event_name: "created", dialog: Dialog {options: {…}, element: …}, params: {options: {…}}
event_name: "initialized", dialog: Dialog {options: {…}, element: …}, params: {}
event_name: "open", dialog: Dialog {options: {…}, element: …}, params: {}
event_name: "shown", dialog: Dialog {options: {…}, element: …}, params: {}
event_name: "loading", dialog: Dialog {options: {…}, element: …}, params: {url: "/admin_ex/popup/"}
event_name: "loaded", dialog: Dialog {options: {…}, element: …}, params: {url: "/admin_ex/popup/"}
event_name: "submitting", dialog: Dialog {options: {…}, element: …}, params: {method: "post", url: "/admin_ex/popup/", data: "text=&number=aaa"}
event_name: "submitted", dialog: Dialog {options: {…}, element: …}, params: {method: "post", url: "/admin_ex/popup/", data: "text=111&number=111"}
event_name: "closed", dialog: Dialog {options: {…}, element: …}, params: {}

You can also trace all events in the console setting the boolean flag enable_trace.
