javascript Dynamic HTML table row causing issues

I have a select option on select of which I am creating an HTML table, As I am calling data from back-end on the basis of selected option so created table rows are dynamic

what I am doing is

• On change of select option I am creating HTML table row, the rows are dynamic and are consist of input fields, ItemName is an auto complete so when I am selecting any item name and focusing out I am getting some corresponding value of that item and populating them in other Input fields
• After selecting ItemName I am shifting my focus on pur. rate then UnitQty after and then Disc% in between these there are some calculations going on and lastly when I press enter on Disc% I am creating new row and everything is same for new row the working process is same

What is my issue

• As doing above process suppose for drop-down selected option Supplier 1 I was doing all that, but then I realize I have to do it for another supplier, i.e. here it is Supplier 2, So on selection of Supplier 2 I am deleting tbody and tfoot and creating fresh one

• So after drop-down change new row is created and it should work same as above, but what's happening is for 1st row it is taking right data, but when on Disc% I press enter to create new row it creates a new row, but ItemName is taking other supplier data like for supplier 2 it is taking supplier 1 data in second row

Please check my snippet I have putted alert and comment for better understanding of the issue
