.validator('update') 不适用于动态添加的字段

Question

我正在使用 Bootstrap（插件）：validator.js v0.11.9 bootstrap validator 在 Python 中进行字段验证项目 （Python 3.6 版和 Django 1.11 版）。在按钮 click 上，我使用 jquery -

在表单中添加了几个字段

JQuery :

 $("#button1Id").click(function(){
    $("#divInsideFormId").append('filed1-selectoption, field2-datepicker, field3-textbox');             
});

根据文档 validator fields

默认情况下，验证器只会验证插件初始化时存在的字段。如果您的表单有一组动态字段，您将需要调用 $(...).validator('update') 来通知插件要验证的字段集已更改。

我尝试了以下 -

$("#button1Id").click(function(){
    $("#divInsideFormId").append('filed1-selectoption, field2-datepicker, field3-textbox');
    $("#formId").validator('update');           
});

这没有用。我也试过了 - $("#divInsideFormId").append(...).validator('update');

即使这样也行不通。

任何人都可以建议我的代码有什么问题或者我是否遗漏了什么？

这是一个工作片段：

$("#button1Id").click(function(){

    var html = '<label for="inputName" class="control-label">New numeric field</label><input type="number" class="form-control" id="inputNum" placeholder="new num field" required>';
    $("#divInsideFormId").append(html);
    $("#formId").validator('update');           
});
