Angular 2 – ngModel不检查Checkbox

我现在拥有的是：

在复选框的标签旁边有SVG(复选框将隐藏在生产中,现在在plunkr中可见,用于调试目的)

但当我点击“女性”时,它会将焦点更改为复选框而不是检查它.

码：

CSS

svg { 
  width: 15px; height: 15px;

  border: 2px solid #a13b4a;
}
label {
  display: inline-block;
  padding-left: 1.5em;
  position: relative;
  cursor: pointer;
  color: black;

}
input[type="checkbox"] {
  opacity: 0;
  width: 15px;
  height: 15px;
}
label svg path {
  transition: stroke-dashoffset .4s linear;
}
input[type="checkbox"]:checked ~ label svg path {
  stroke-dashoffset: 0;
}
input[type="checkbox"]:checked ~ label {
  color: #a13b4a;
}
