    var url_full=url+vars+"&t=" + Math.random();

    hr.open("GET",url_full,true);

    hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");

   hr.onreadystatechange = function() {
       if(hr.readyState == 4 && hr.status == 200) {
           var return_data = hr.responseText;
            document.getElementById("dash-content").innerHTML = return_data;

您无法附加click处理程序，[data-switch='true']因为加载页面时它不存在。您必须将其附加到#dash-content：

$('#dash-content').on('click', '[data-switch="true"] .btn', function() {
    // your code
});

首先，您所有的按钮都具有相同的 id id="12"。您正在触发点击这些按钮。这可能会导致问题。请更改它们。

<button type="button" class="btn btn-small btn-info active" id="12" ..
<button type="button" class="btn btn-small" id="12    ...            
<button type="button" class="btn btn-small" id="12"  ....

这是副作用。对于点击事件问题，请查看@Billy 答案
