动态添加的元素未在首次点击时删除

Question

我在select事件的html页面中添加元素，它工作正常但是当我点击删除图标对应的元素时，单击一下就不会删除它。但是当我点击两次时它会被删除。

function addToFilter(divName) {
  console.log(divName);
  var val = document.getElementById('filter').value;
  var newdiv = document.createElement('div');

  switch (val) {
    case 'mcus':
      newdiv.innerHTML = "<div class='container'>Multi company use case &nbsp: " +
        "&nbsp;<select id='mcuc_selection'>" +
        "<option value='select'>--select--</option><option value='ags'>AGS</option><option value='agl'>AGL</option><option value='nafn'>NAFN</option></select>" +
        "&nbsp;&nbsp<img src='remove-icon.jpg' alt='remove' onclick='removeFilters();' onmouseover='' style='cursor: pointer;' class='remove-icon'>" +
        "<hr style='width:900px; margin-left:0px;'></div>";
      break;

    case 'oc':
      newdiv.innerHTML = "<div class='container'>Order Condition &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;:" +
