                  {{/for}}

Solution

Helpers

You can pass the s_name variable as a helper.

See http://www.jsviews.com/#helpers

For example:

var helpers = {
    s_name_Hlpr: s_name,
  ...};

myTmpl.render(data, helpers);

Then write:

<input type="radio" name="{{:s_name_Hlpr}}" ... />

Allow Code

Alternatively (but better avoided) you can allow code access in your template:

See http://www.jsviews.com/#allowcodetag

First set:

$.views.settings.allowCode(true);

Then write:

<input type="radio" name="{{*:s_name}}" ... />

Contextual parameters

That said, it looks like you're are trying to initialize your s_name from data.

var s_name = "{{:Name}}";

You may really be wanting to pass in the Name from the product, which you can do like this:

{{for Product}}
  ...
  {{for Options ~prod_name=Name}}
    ...
    {{for Features}}
      ...
      <input type="radio" name="{{:~prod_name}}" .../>
      ...
    {{/for}} 
    ...
  {{/for}} 
  ...
{{/for}} //products
