用angularjs绑定单选按钮和输入文本域

我对这段代码有一些问题，并且卡住了。我试图显示两个答案(从两个问题)在只有一行和动态在底部"你的答案"之后，所以他们动态地改变，如果用户改变选择无论是在单选按钮或下拉菜单。到目前为止我只能显示一个答案。此外，在选择输入文本字段中有一个错误。当用户输入时，应该显示1个秋天，2个春天等等，但现在它只适用于从0到3的数字，而不是1到4。我尝试了不同的方法来解决这个问题，但都没有成功

var app = angular.module('myApp', []);
            app.controller('myCtrl', function($scope) {
                $scope.actresses = [
                    {model : "Jenna"},
                    {model : "Mia"},
                    {model : "Julia"},
                    {model : "Olivia"}
                ];
                $scope.quarters=[
                    {model : "fall", number : 0},
                    {model : "spring", number : 1},
                    {model : "summer", number : 2},
                    {model : "winter", number : 3},
                ];
        $scope.change = function(a){
            console.log(a);
            $scope.selectedQuarter= $scope.quarters[a];
            console.log($scope.selectedQuarter);
        };
    });
