listbox values from FormItCountryOptions

I wanted to get country select box from FormItCountryOptions snippet.

Now when I put input options value in template variable as
@EVAL return $modx->runSnippet('FormItCountryOptions');

I got output for that tv as <option value="AF">Afghanistan</option> <option value="AL">Albania</option> <option value="DZ">Algeria</option> etc.

I want only display country name in listbox.
