Describe the bug

I want to render an integer enum control as a radio via the following schemas:

schema.json

"amount": {
  "type": "integer",
  "enum": [50, 100, 250, 500]
}

uischema.json

{
  "type": "Control",
  "scope": "#/properties/amount",
  "options": {
    "format": "radio"
  }
}

The issue is now that apparently the values of the radio inputs are converted/considered to be string instead of integers. Because of that i cannot select any of the values because the validator is righfully complaining that the selected values are not valid.

Expected behavior

The radio group values should be selectable

Steps to reproduce the issue

1. Provide schema as outlined above
2. Try to select one of the options
