Is App Connect two way data binding?

I’m using a Data Detail component to display record detail and one of the fields is an array of objects, or child records for the parent. I’m displaying them on a form that the user can interact with. When the user changes a value in one of the inputs, does the underlying object or value (in the Data Detail) get updated?

I have a sum of two values from the Data Detail child records (Quantity*Price) but when I change the quantity or price, the sum is not updated and I’m wondering how to get it to work.
