Google Chrome Bookmarks API

问题

I'm creating a Chrome Extension that can saves and retrieves bookmarks specific only to the user. Bookmarks are stored in the local disk in a form of a file. So I use the bookmarks API of Google Chrome. But somehow their sample code doesn't work for me.

function bkmk(){
                    chrome.bookmarks.create({'parentId': bookmarkBar.id,
                     'title': 'Extension bookmarks'},
                    function(newFolder) {
                    alert(newFolder.title);
                    });
                }

I trigger the function with an onclick event on a button.... Is there something wrong with this? Note: I already gave permission to Bookmarks API in the manifest.

Edited to add OP's comment

oh.. this one is fine now... I just used a wrong entry for the folder ID.. I used a non-existing ID of a bookmark node that's why it did not create a bookmark/folder... now my concerns are a.) how to tell chrome not to add the bookmarks in the default user but rather insert the bookmark in a file generated by my extension and b.) how to load the bookmarks to the bookmarks bar using the file generated by my extension instead of loading the default user's bookmarks?????
