.validator('update') not working for dynamically added fields

Question

I am using Bootstrap (plugin): validator.js v0.11.9 bootstrap validator for field validations in a Python project (Python version 3.6 and Django version 1.11). On a button click I have added couple of fields to the form using jquery -

JQuery :

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

According to the docs validator fields

By default, the validator will only validate fields that are present when the plugin is initialized. If your form has a dynamic set of fields, you will need to call $(...).validator('update') to inform the plugin that the set of fields to be validated has changed.

I tried the following -

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

This did not work. I also tried - $("#divInsideFormId").append(...).validator('update');

Even this isn't working.

Can anyone suggest what's wrong with my code or if I am missing something?

This is a working snippet:

$("#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');           
});
