angular - 如何从 angular2-toaster closeHtml 激活组件功能

Question

我想从ToasterConfig closeHtml属性中激活组件功能或服务功能。我怎样才能到达正确的上下文（组件的 this ）以到达组件功能？这是配置的样子：

componenet :...
    someAngular2-ToasterConfig = new ToasterConfig
    (
        {
            positionClass=<some CSS Class name>, 
            showCloseButton: true,
            closeHtml:'<button type="button" onclick="dosomething()">click here to do something 1</button><button type="button" (click)="dosomething()")>click here to do something 2</button>'
        }
    );
    
    dosomething()
    {
        ...
    }
