Bootstrap 4-将按钮插入Popover无效

Question

我正在尝试将2个按钮插入由.clear-history按钮触发的弹出窗口：

<div class="modal-footer text-nowrap">
    <button type="button" class="clear-history btn btn-link">Clear history</button>
</div>

---

const clearHistoryBtn = `
    <span>All records will be removed</span>
    <button type="button" class="confirm-clear-history btn btn-sm btn-danger">Yes</button>
    <button type="button" class="btn btn-sm btn-link">No</button>
`;
$('.clear-history').popover({
    placement: 'bottom',
    html: true,
    title: 'You are cleaning the history',
    content: clearHistoryBtn
});

但是在弹出框内只有文本：

我想知道它是否与模式有关

    <button type="button" class="btn btn-sm btn-link" onclick="alert('event raised from no button');">No</button>
`;

    html: true,
    title: 'You are cleaning the history',
    content: clearHistoryBtn
});
