Add a push method and table sort filters in Angular -- 2

I have already created an Angular project. On it I want to add a method by which I can push a new book (name, author name, date added) to that table. There is a method that you can see under the table and in the second printscreen, but it doesn't work. You can delete it and create another one.

I also want 2 filters to sort the table (sort alphabetically by book name and sort by date added). That's all.

You can download the project and work on it directly from git https://github.com/axc1505/Book-Store

I'm sure if you know how to do it, it won't take you more than two hours.

MAXIMUM BUDGET 15$
