title: how to specify dynamic scope object in ng-repeat
body: <p>I have a html code </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;tr ng-repeat='row in po123'&gt;
             &lt;td&gt;{{row.buyerLineItemNumber}}&lt;/td&gt;
             &lt;td&gt;{{row.buyerPartNumber}}&lt;/td&gt;
             &lt;td&gt;{{row.supplierPartNumber}}&lt;/td&gt;
             &lt;td&gt;{{row.itemDescription}}&lt;/td&gt;
             &lt;td&gt;{{row.itemQuantity}}&lt;/td&gt;
             &lt;td&gt;{{row.itemQuantityUOM}}&lt;/td&gt;
             &lt;/tr&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>and a scope element </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-html lang-html prettyprint-override"><code>var poNumber = "123";
  $scope.poNumber = poNumber;
   $scope["po"+poNumber] = [{'buyerLineItemNumber':'12121','buyerPartNumber':'buyerPartNumber','supplierPartNumber':'supplierPartNumber','itemDescription':'itemDescription','itemDescription':'itemDescription','itemQuantityUOM':'itemQuantityUOM'}];</code></pre>
  </div>
  </div>
  </p>
  
  <p>In the appication poNumber is dynamically generated and is available as a $scope value and i create a dynamic scope element using the poNumber . How can i use this dynamic created scope element in ng-repeat.</p>
  
  <p>if i specify statically as in the code snippet it works fine, i want to specify something like<code>&lt;tr ng-repeat='row in "po"+{{poNumber}}'&gt;</code></p>
  
  <p>how can i achieve this?</p>
