回答1:

All you have to do is set the observable

success : function(responseData) {
    var data = ko.toJS(responseData);
    AppViewModel.agent(data.agent);
}

回答2:

You can just assign new data to array:

success : function(responseData) {
    var data = ko.toJS(responseData);
    AppViewModel.agent(data);
}
