Change the pagename for bookmark in UI

Hi Team,

I used the below code Jquery UI for bookmark and I want to change page name  every time. Can you please provide the sample code to change page name??

var bookmarkControl = $('#bookmarkControl');
bookmarkControl.evolutionBookmark({
    initialState: true,  // content is bookmarked
    contentId: 'C512D1A1-ED6C-442D-BC9d-3587CD711D35',
    contentTypeId: 'F7D226AB-D59F-475C-9D22-4A79E3F0EC07',
    contentTypeName: 'Blog Post',
    onBookmark: function(contentId, contentTypeId, typeId, callback) {
        alert(contentId + ' bookmarked!');

        // ...perform AJAX-based saving of bookmark here...

        // After a successful save, callback to notify the bookmark plugin
        callback();
    },
    onUnbookmark: function(contentId, contentTypeId, typeId, callback) {
        alert(contentId + ' unbookmarked!');

        // ...perform AJAX-based saving of bookmark here...

        // After a successful save, callback to notify the bookmark plugin
        callback();
    }
});

Regards,

Kiran.
