下拉引导程序内的单选按钮

Question

我有来自bootstrap的下拉列表：

我在下拉列表中插入单选按钮但是如果你可以看到dosnt里面的单选按钮有样式，我想在下拉列表中显示单选按钮时颜色相同。

这是来自下拉列表的html：

<div class="btn-group dropdown todos" id="todos">
            <button class="btn btn-default dropdown-toggle botn-todos" type="button" id="dropdownMenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Todos
            <span class="caret caret-posicion"></span>
            </button>
            <ul class="dropdown-menu ancho-todos" aria-labelledby="dropdownMenu1">
              <li><a href="#" ><input value="1" name="busqueda1" type="radio" class="todoss"><span> Todos</span></a></li>
              <li><a href="#"><input value="1" name="busqueda1" type="radio" class="enc"> En camino</a></li>
              <li><a href="#"><input value="1" name="busqueda1" type="radio" class="enca"> En camino - 2do intento</a></li>
              <li><a href="#"><input value="1" name="busqueda1" type="radio" class="entre"> Entregado</a></li>
              <li><a href="#"><input value="1" name="busqueda1" type="radio" class="entre2"> Entregado al 2do intento</a></li>
              <li><a href="#"><input value="1" name="busqueda1" type="radio" class="nose"> No se puede entregar</a></li>
              <li><a href="#"><input value="1" name="busqueda1" type="radio" class="cancelado"> Cancelado</a></li>
            </ul>
          </div>

这是我点击项目时的脚本代码：

$('.dropdown-menu').on( 'click', 'a', function() {
                var text = $(this).html();
                alert(text);
                var htmlText = text + ' <span class="caret caret-posicion"></span>';
                $(this).closest('.dropdown').find('.dropdown-toggle').html(htmlText);
            });

这是每个单选按钮的css：

li:first-child input[type='radio']{
    -webkit-appearance:none;
    width:15px;
    height:15px;
    border:3px solid #6a706d;

    margin: 0 13px -3px 0;

    }
    li:first-child input[type='radio']:before {
