Access parent data in html

Hi first of all thanks for the great work.

I have a problem I need to access the parent template data on the server side. this is my code:

in the private folder i have this HTML

```
{{#each categories _id}}
{{#each recipes }}

{{category.nameIt}}

{{nameIt}}

{{/each}}
{{/each}}
```

and I defined recipes like this (in the server's method I call):

```
recipes: function(){
var cId = Template.parentData(0)._id
return Recipe.find({"categoryId": cId, "isActive": true});
}
```

`Template.parentData(0)._id` doesn't work.
