title: SAPUI5 get binding context of row by index
body: <p>In my application I have a sap.m.table. The data is in a JSON model and bound to the table. In my function I need to loop all table rows and check each visible row for the value of a specific property. I can determine the visible rows like this:</p>
  
  <pre><code>sap.ui.getCore().byId("myTableId").getAggregation("items")
  </code></pre>
  
  <p>However, I was not able to use some function like <code>getBindingContext</code> to determine the property values of the row.</p>
  
  <p>Any hint how to do that? </p>
