How to enter innerHtml to an input (generated with TagHelper)?

I created my own anchor tag using MVC 6 Tag Helper. It works fine if I give the innerHtml from a property but I want to give the innerHtml directly from HTML. Here is my TagHelper code for the custom anchor

   public string Text { get; set; }  

   public override void Process(TagHelperContext context, TagHelperOutput output)
   {
       var builder = new TagBuilder("a");

       output.Attributes.Add("data-controller", Controller);
       output.Attributes.Add("data-action", Action);

       if (!string.IsNullOrEmpty(Text))
       {
           builder.InnerHtml.Append(Text); // INNER HTML IS HERE!!! 
       }
       builder.AddCssClass("btn btn-link");
       output.Content.SetContent(builder);
       base.Process(context, output);
   }

And the usage is like this now (Current situation - it works)

<anchor-box name="ALink" controller="A" action="D" text="innertext From Here"></anchor-box>

Is it possible to give the inner html text directly while using in the cshtml like the following? (Needed situation - currently not works)

<anchor-box name="ALink" controller="A" action="D">Directly Here</anchor-box>

Any help appreciated
