Answer 1

$('#Characteristics').append(partialView);

If you use Id selector, it will always select the first element with the id Characteristics .

Try the below codes:

function add(element){
        var action = ' @Url.Action("NewIndividualSearchCharacteristic", "Blended")';
        $.post(action)
        .done(function (partialView) {
            element.previousElementSibling.append(partialView);
        });
}
