In html file, i could show the billing address prefix with text: currentBillingAddress().prefix. But when i tried to give data-bind to input, it become <input type="hidden" id="test2" data-bind="text: currentBillingAddress().prefix"/>Prefix</input>.
How can i set the value of input to billing address prefix? I already tried <input type="hidden" id="test2" input="text: currentBillingAddress().prefix"/> but it's not work.
