the for attribute in label is wrong. It should not rendered by radio buttons

<div class="form-group">
    <label class="control-label" for="kontakt-radiobutton-1">Radio button</label>
    <div class="input">
        <div id="kontakt-radiobutton-1" class="inputs-list">
            <div class="form-group">
                <div class="form-check">
                    <label class="form-check-label">
                        <input class="xlarge form-check-input" type="radio" name="tx_form_formframework[kontakt][radiobutton-1]" value="1" /><span>Wert 1</span></label>
                </div>
                <div class="form-check">
                    <label class="form-check-label">
                        <input class="xlarge form-check-input" type="radio" name="tx_form_formframework[kontakt][radiobutton-1]" value="2" /><span>Wert 2</span></label>
                </div>
                <div class="form-check">
                    <label class="form-check-label">
                        <input class="xlarge form-check-input" type="radio" name="tx_form_formframework[kontakt][radiobutton-1]" value="3" /><span>Wert 3</span></label>
