Does that help You can wrap or extend the input element and put your code in the attached or ready lifecycle method or use MutationObserver.

In polymer-dart how do I count inside a repeating template

Hope this helps I'm adding some utilities to Fancy Syntax (Polymer.dart's default binding syntax now) to help with this, but the basic outline is to run your collection though a filter that will add indices and return a new Iterable.
Here's some code that will do it now though:
code :
import 'package:fancy_syntax/fancy_syntax.dart';
import 'package:mdv/mdv.dart';

Iterable<IndexedValue> enumerate(Iterable iterable) {
  int i = 0;
  return iterable.map((e) => new IndexedValue(i++, e));
}

class IndexedValue<V> {
  final int index;
  final V value;

  IndexedValue(this.index, this.value);
}

main() {
  query('#my-template')
    ..bindingDelegate = new FancySyntax(globals: {
      'enumerate': enumerate,
    })
    ..model = ['A', 'B', 'C'];
}
<template bind id='my-template'>
  <template repeat="{{ item in this | enumerate }}">
    This is the bound value: <span id="#myid-{{ item.index }}">{{ item.value }}</span>
  </template>
</template>

hope this fix your issue Ok I found what was wrong: when using conditional template you need to use a master template to encapsulate conditional templates:
code :
<polymer-element name="click-counter">
<template>
  <template if="{{count < 10}}">
    ...
  </template>
  <template if="{{ count >= 10 }}">
    ...
  </template>
</template>
<script type="application/dart" src="clickcounter.dart"></script>
</polymer-element>
In Polymer.js children of a template have a reference to the template, how can this be done in Polymer.dart
