Fire event for new rows added to a table

I am new to jQuery, but can find my way around if someone can please help me.

I have a table where user can add rows on button click. That button calls controller method, so I cannot implement onclick there. Each row would have input fields qty and price. Formula field total price (qty * price).

I have a function which calculates the total price when user changes the fields. I would like to call that function when any new row is added to a table.
