22. Within the sharePointReady function, change the createItems(); call to updateListItem();.

23. Directly after the sharePointReady function, insert the following code: var updatedItem; function updateListItem() { var listContext = new SP.AppContextSite(context, hostUrl); var list = listContext.get_web().get_lists().getByTitle('My Sample List'); var listItem = list.getItemById(1); listItem.set_item('Title', 'Updated via JS CSOM'); listItem.update(); context.load(listItem); context.executeQueryAsync(onUpdateItemSucceeded, onFailed); } function onUpdateItemSucceeded() { alert('Updated item!'); }
