EJS Template: Using forEach + include

I have many files in a Folder in want to include in a Template (EJS).

I try this:

 <% var test = ["foo.ejs"];
 _forEach(test, function(item){ %>
      <% include slides/item %>
  <% }); %>

I would use Nodejs to fill the Array by looking in a folder.

But i get the error:

 Error: ENOENT, no such file or directory 'app/views/slides/item.ejs'

It seems that ejs dont use "item" as a variable.
