Hey guys, I am creating a TinyMCE button - very similar to EPiLink button. I need to hook to page-selected/page-changed, this does not work:

linkEditor.on("fieldCreated", function (fieldname, widget) {

                                if ("href" === fieldname) {
                                    var hyperLinkSelector = widget,
                                        anchor = null,
                                        anchorWidget = getAnchorWidget(hyperLinkSelector.wrappers);
                                    anchorWidget && anchorWidget.length > 0 && (anchor = anchorWidget[0]), anchor && anchor.inputWidget ? anchor.inputWidget.set("selections", anchors) : widget.on("selectorsCreated", function (hyperLinkSelector) {
                                        var anchorWidget = getAnchorWidget(hyperLinkSelector.wrappers);
                                        anchorWidget && anchorWidget.length > 0 && anchorWidget[0].inputWidget && anchorWidget[0].inputWidget.set("selections", anchors)
                                    }), anchor && domStyle.set(anchor.domNode, {
                                        display: "block"
                                    });

                                    var page = null,
                                        pageWidget = getPageWidget(hyperLinkSelector.wrappers);
                                    pageWidget && pageWidget.length > 0 && pageWidget[0].inputWidget && pageWidget[0].inputWidget.onChange(function () {
                                        var test = "aaa";
                                    }) &&
                                    on(pageWidget[0].inputWidget, "onchanged", function() {
                                        var test2 = "bbb";
                                    })
                                    ;
                                }...

getPageWidget is similar as getAnchorWidget:

getPageWidget = function (widgetList) {
                                    return array.filter(widgetList, function (wrapper) {
                                        return "Page" == wrapper.name;
                                    });
                                }

and it is getting the correct widget, my hope is that the name of the event is wrong. Breakpoint doesn't get hit when I select the page in the tree and the dialog closes. If anyone knows how to hook to dialog closed from the same file, it's also of great help.
