Получить значение идентификатора в модели

---

всем привет,

I want to set in parameter of my Onclick function the value of the ID of each data recovered in my model

когда я пытаюсь, что у меня есть ошибка, как :

Invalid or unexpected token

Что я уже пробовал:

<pre>@model List<sotels.smartretail.common.Tenant.SaleDetailVM>
