Icon with ejs-textbox

Hi, 

I am new to Syncfusion and have 2 questions:

1. According to the documentation, I see that using Syncfusion TextBox for ASP.NET core can be performed in at least 2 ways. First is to use <ejs-textbox> tag helper, and second one is to use regular html tags with proper classes. Is there preferable way to use the control since as I can see that for same effect to be achieved <ejs-textbox> encapsulates some styles and scripts (for example ripple effect) while if using html tags this script must be included too?

2. Can I use icons (font awsome or other) with Syncfusion TextBox more easily then in the documentation example, where icons are added through custom style and script without using <ejs-textbox> tag helper? I don't see that <ejs-textbox> has it implemented.

<div class="control-section">      <div class="control_wrapper accordion-control-section">          <ejs-textbox id="default" placeholder="Enter date" created="onCreateIcon"></ejs-textbox>      </div>  </div>    <script>      function onCreateIcon() {          var textboxObj = document.getElementById("default");          textboxObj.ej2_instances[0].addIcon("append", "e-date-icon");      }  </script>
