编辑器模板重复 - applyBindings？

Question

当我提交表单时，foreach：整数正在复制我的编辑器模板。有人知道为什么吗？

e.g。假设我提交了5个整数，当我点击添加按钮时，将添加5个编辑器模板而不是1。

剃刀：

<div data-bind="foreach: integers">
    @Html.EditorFor(model => model.Integers)
</div>
<input name="btn" type="button" data-bind="click: addInteger" value="+" />
<input name="btn" type="button" data-bind="click: removeInteger, enable: integers().length > 2" value="-" />

编辑模板：

@model IntegerSorter.Models.IntegerViewModel
<div class="input-group">
@Html.TextBoxFor(
    m => m.IntegerValue,
    new { 
        @class = "text-box single-line text-input large-input",
        type = "number",
        data_bind = "value: name,
                uniqueName: true,
               valueUpdate: 'afterkeydown',
                      attr:
                          { 
                              id: 'Integers_' + $index() + '__IntegerValue',
                            name: 'Integers[' + $index() + '].IntegerValue'
                          }"
    }
)
@Html.ValidationMessageFor(model => model.IntegerValue)
</div>

淘汰赛：

        var viewModel = {
            integers: ko.observableArray([
                { name: ko.observable(), value: "0" }
            ]),
            addInteger: function () {
                this.integers.push({
                    name: ko.observable()
                });
            },
            removeInteger: function () {
                this.integers.pop({
                    name: ko.observable()
                });
            },
            save: function () {
                ko.utils.postJson($("form")[0], integers);
            }
        };
        ko.applyBindings(viewModel);
