can't access parental data context (meteor/blaze)

Question

I'm trying to figure out how to use dynamic templates correctly in my meteor application.

First, I have a set of templates to be inserted dynamically, e.g. moduleSearch, which contains a search form:

template(name='moduleSearch') 
    input(placeholder='search', type='text')

My header template looks as follow:

template(name='header')
    each modules
      li
        +UI.dynamic template=this data=objectsList

Each of the yield templates includes the header template with a dynamically changing set of modules, depending on the current yield template. E.g. My objectsList template..

template(name='objectsList')
  +UI.dynamic template='headerYield' data=modules

..includes the moduleSearch template:

Template.objectsList.helpers({

  modules: function() {
    return ['moduleSearch'];
  }

All the templates are displayed properly, as expected. The moduleSearch template contains a search form, to query the collection items at the objectsList template, however, it doesn't work. How can I get the parental context (access objectList's data & helper functions from moduleSearch)?

PS - When I copy-paste the content of the moduleSearch template into the objectsList template, the search feature works, data is being filtered reactively in this case.

You pass the datacontext into the helper

{{> mysubtemplate parentdatacontext=datacontext}}
