Add dynamic data to the choice group

<choice>
                    <choiceRadiogroup value="3" id="accno">
                        <_value>@{gender}</_value>
                        <radiobutton value="1">123456</radiobutton>
                        <radiobutton value="2">234567</radiobutton>
                        <radiobutton value="3">345678</radiobutton>
                    </choiceRadiogroup>
                </choice>

In the above code i want the data 123456 in the radiobutton tag to be dynamic(which is coming from the server). I am very new to Kuix. Can anybody tell me how to do this
