为什么我判断后男女性别都出来了

 <tr align="center"><td width="50%" align="right">性别： </td>
            <td align="left">
            <c:choose>
                <c:when test="${manager.sex == 1}"><input type="text" id = "Sex"  value = "男" name = "observer.sex" /></c:when>
                <c:otherwise> <input type="text" id = "Sex"  value = "女" name = "observer.sex"/> </c:otherwise>
            </c:choose>
            </td>
            </tr>
