localytics angular-selected no-results-text with button

Question

如果搜索到的值不在列表中，我需要将搜索到的内容添加到列表中。 在无结果文本中我能够插入输入元素，但该元素中的ng-click功能不起作用。

使用按钮搜索未列出的项目后的屏幕截图： Screenshot

示例代码段，搜索未列出的项目。您将在下拉列表中看到添加按钮。 问题是没有调用添加按钮功能。

控制器：

  angular.module('test',['localytics.directives'])
  
  .controller('ctrl',function($scope){

    $scope.noResultsText ="'<input id=\"BtnId\" type=\"button\" value=\"add\" ng-        click=\"ClickFunction(searchValue)\" />'"

    $scope.ClickFunction=function(searchValue){
    alert(searchValue);
    }
    
    $scope.alphabets=['a','b','c','d'];
    
    })
