custom radio button not working

[iamalex2]

this is what I tried, but not working... "required, class, title" for radio buttons in ember-cli
{{#each field.proxiedValues as |val|}}
{{csp-radio
name=field.key
value=val.value
groupValue=field.value
checked=field.value
required=true
class="required"
title="Please select an option"
}}
{{val.label}}
  
{{/each}}
