将内部值嵌套为每个外部对象的关键：车把

Question

I am making a help to use for multi-col tables. In the helper you specify which object columns you want to display and with nested each loops it should all work. I have the values I need where I want them but I can't get handlebars to use the inner string value as a key for the outer value.

I have an almost working PLNKR here with all the code in it. which you can play around with.

It almost works..

The short part of the code where I'm having an issue is:

<table>
 {{#items}}
  <tr >
    {{#each ../colNames}}
      <td>{{../this}}.{{this}}</td>
    {{/each}}
    <td>
      <input type="checkbox" 
        id="masterList{{@index}}"
        {{#if this.selected}}checked{{/if}}
        onchange="{{../checkAction}}({{@index}})"
      >
    </td>
  </tr>
 {{/items}}
</table>

Even more specifically:

<td>{{../this}}.{{this}}</td>

I have tried things like:

<td>{{../this}}.[{{this}}]</td>
<td>{{../this}}.[this]}}</td>
<td>{{../this.this}}</td>
<td>{{../this.(this)}}</td>

The closest I get returns like (with column names given to the helper "name" and "score"):

<td>[object Object].name</td>   
<td>[object Object].score</td>

Thanks in advance for any ideas to solve or work around this.
