Handlebars.js: nested iteration with ability to access parent

One simple approach would be to register a helper:

{{#each animals}}
  {{#each organs}}
    {{get .. this}}
  {{/each}}
{{/each}}

Handlebars.registerHelper('get', function(obj, prop) {
  return obj[prop];
});

Sorry to bring this issue back up, but I don't see how this 'get' helper will give access to the parent unless we create circular references.

Could you expand on what you mean by "{{get .. this}}"? If this is an organ, how can we use that to find the parent animal?

I would like to use handlebars.js to iterate over a list of families, and then iterate over that family's members. Inside of both loops, I want to display properties of both. However, once I get into the second iteration, none of the family variables are visible.

{{#each families}}
  {{#each members}}
    <p>{{ ( here I want a family name property ) }}</p>
    <p>{{ ( here I want a member name property ) }}</p>
  {{/each}}
{{/each}}

Is this possible with handlebars? If not, that's OK. I'd greatly appreciate any help!

{{#each families}}
  {{#each members}}
    <p>{{ ../surname }}</p>
    <p>{{ name }}</p>
  {{/each}}
{{/each}}
