title: How to bind to data-* attribute in angular2?
body: <p>Assuming I have really large grid of cells I want to add data-row and data-col atribute values and bind from model. How can I bind data-row from angular2 (beta0 in Dart).</p>
  
  <p>Binding with data-row="{{boundVal}}" does not seem to work.
  (no data attribute appears in output html)</p>
  
  <p>eg.</p>
  
  <pre><code>&lt;table&gt;
    &lt;tr *ngFor="#row of rows" &gt;
        &lt;td *ngFor="#cell of row.cells" data-row="{{row.index}}" data-col="{{cell.index}}" &gt;
        &lt;/td&gt;
    &lt;/tr&gt;
  &lt;/table&gt;
  </code></pre>
