title: SAPUI5 Can't access a array and give it to a JSONModel
body: <p>I have problems to access an array, where i put some data from a omodel read. The array is called aData und contains row data for a table. This works fine, all data is in there.</p>
  
  <p>This all code is done after a value help dialog is opened and in his/this table i want to put the data</p>
  
  <pre><code>        var oTestModel = this.getModel();
          oTestModel.read("/shrhelpSet", {
              filters: [oFilterObject, oFilterField, oFilterLang],
              success: function(oRetrieveResults){
                  //console.log(oRetrieveResults);
  
                  var oDatas2 = oRetrieveResults;
                  var test1 = oDatas2.results;
  
                  var aData = [];
                  var index = oDatas2.results.length;
                  var i;
                  for (i=0; i&lt;index; i++) {       
  
                      aData.push("{Key: '" + oDatas2.results[i].key + "', Value: '" + oDatas2.results[i].value + "'}");
                  }
  
                  // aData Array  
                  console.log("aData: " + aData);
  
              },
  
              error: function(oError){
                  console.log(oError);
              }
          });
  </code></pre>
  
  <p>This code is after the omodel read. Here i have an array with column data for my table. 
  The oModel2 contains the columndata, which i definded in aColumnData
  and the rows from above are in aData. And here is the problem. It returns (the array) no data or is showing only object. Do you have tipps for better handling this or a solution for this problem?</p>
  
  <pre><code>        var aColumnData = [{
              columnId: "Key"
          }, {
              columnId: "Value"
          }];
  
          var oModel2 = new sap.ui.model.json.JSONModel();
  
          oModel2.setData({
              columns: aColumnData,
              rows: aData // THIS IS THE RESULT OF MY MODEL, the results are in aData but i cant access it here
          });
  
          oTable.setModel(oModel2);
  
          oTable.bindColumns("/columns", function(index, context) {
              var sColumnId = context.getObject().columnId;
              return new sap.ui.table.Column({
                  id : sColumnId,
                  label: sColumnId,
                  template: sColumnId
              });
          });
          oTable.bindRows("/rows");
