Polymer 1 nested dom-if within dom-repeat not updating when data changes

Question

How do you make dom-if templates within dom-repeat\'s update when the data changes??

Example here http://jsbin.com/xatala/edit?html,output<

Answer 1

Here is example that works: http://jsbin.com/nejadibuju/edit?html,console,output

<template is="dom-if" 
  if="{{arrayItem(myItems.*, index, 'isGood')}}">
      [[item.title]] is SOOO good.
</template>

What you were missing is:

Explicit bindings to array items by index isn’t supported
