Aspnetcore.docs: Example uses "For internal use only" method

[mrlife]

The InputText based on the input event section uses CreateBinder(), which is labeled as "For internal use only."

Please update with a safe alternative. See https://github.com/dotnet/aspnetcore/issues/24883#issuecomment-710099785 for a related discussion.

Thanks @mrlife ... Let's ask ..........

@pranavkm @SteveSandersonMS ... The original version of this (it was updated at least once along the way) was a Ryan bit that came at 3.0 Preview 9 ...

• Issue: [Preview 9] Add sample for InputText with oninput (dotnet/AspNetCore.Docs #13912)
• PR: Add sample for InputText with oninput (dotnet/AspNetCore.Docs #14123)

Do you want to keep it, replace it, or 🔪💀 _kill it?_ 💀🔪

@SteveSandersonMS can you please look into this and see whether there is an alternative API we can use in this sample? Thanks!

@guardrex Do you remember any details about why the sample was written that way? My first thought is there's no obvious reason to use EventCallback.Factory.CreateBinder here - it looks like it could just use @bind. That is, CustomInputText.razor could be:

@inherits InputText
<input 
    @attributes="AdditionalAttributes" 
    class="@CssClass" 
    @bind="CurrentValueAsString"
    @bind:event="oninput" />

Do you know of some reason that doesn't work?

It looks like it was just a workaround back when Ryan sent it over in August, 2019 (ages ago during Preview 9) ...

OK cool, looks like it could be updated then!

Thank you all, it works great!
