Unable to add sibling node into soap response

Hi everyone i need to generate soap response as following.I have generated it upto "GetTestDetailResult" node.But unable to add "country" as child of root node(GetTestDetailResponse).

<soap:Envelope xmlns:soap="http://ift.tt/sVJIaE">
  <soap:Body>
    <GetTestDetailResponse>
      <GetTestDetailResult>
        <id>string</id>
        <fname>string</fname>
        <lname>string</lname>
      </GetTestDetailResult>
      <country>string</country>
      <age>int</age>
    </GetTestDetailResponse>
  </soap:Body>
</soap:Envelope>

My wsdl file is as follow:
