title: Dynamically Generating Bind Variable Names
body: <p>I have a data grid, in which I use <code>dom-repeat</code> to generate the columns.</p>
  
  <pre><code>&lt;vaadin-grid-filter value=[[filterInput]] /&gt;
   &lt;input value={{filterInput::input}} /&gt;
  &lt;/vaadin-grid-filter&gt;
  </code></pre>
  
  <p>I bind the value used to filter a column with the value input into an input element.</p>
  
  <p>My problem is each column binds to the same <code>filterInput</code> variable.</p>
  
  <p>Is there any way I can bind using a variable for each specific column?</p>
  
  <p>Could I somehow generate the binding variable for each column, e.g. <code>filterInput[0]</code>, <code>filterInput[1]</code> etc. by using the <code>index</code> variable that comes with <code>dom-repeat</code>?</p>
