Add some functionality to MVC .Net application

I have one MVC View which is linked with three tables (Using View Model). I need to create something like invoice where there is a functionality to add new row dynamically with material code drop-down and getting material information based on material code through Ajax and display them in the columns with a textbox to add quantity for the material. As user adds quantity, total price should be calculated. Refer to image 1. On top, user will add Note Basic Information such as Code, Description, and Name etc. This information will be saved in tblReceivingNote. Then there is a table, where user will select material code such as 80041 and it will get all the information related to that material with one textbox to add quantity. As user will add new quantity, I want it to take unit price and multiply with quantity to get total price. As user click on add row, new row should be appended with same above functionality. In the end, as user click on save it loop through material id and quantity and save three things in new table: MaterialId, ReceivingNoteId and Quantity. Likewise, there will be same exact View for the Edit which will show same exact functionality with the existing records and a way to add new rows or delete rows.
