Bootstrap Validator：验证动态无线电

Question

我正在尝试动态输入验证

HTML：

<input type="radio" value="1"  class="job_knowledge" name="job_knowledge[0]" required>
<input type="radio" value="2"  class="job_knowledge" name="job_knowledge[0]" required>
<input type="radio" value="3"  class="job_knowledge" name="job_knowledge[0]" required>

//克隆字段

<input type="radio" value="1"  class="job_knowledge" name="job_knowledge[1]" required>
<input type="radio" value="2"  class="job_knowledge" name="job_knowledge[1]" required>
<input type="radio" value="3"  class="job_knowledge" name="job_knowledge[1]" required>

//克隆字段

<input type="radio" value="1"  class="job_knowledge" name="job_knowledge[2]" required>
<input type="radio" value="2"  class="job_knowledge" name="job_knowledge[2]" required>
<input type="radio" value="3"  class="job_knowledge" name="job_knowledge[2]" required>

当我尝试下载时，

无法验证：
