title: ag-grid api.refreshView() does not seem to be working
body: <p>The data that I load in ag grid depends on an http call and once I get the data I call the api.setRowData(data); and during debugging I see that the data that I need is there. But the grid does not show the entire data at first http response. When I make a second call only then it shows the data. Here is what I do once I get the data from http call:</p>
  
  <pre><code>gridOptions.api.setRowData(data);
  gridOptions.api.refreshView();
  </code></pre>
  
  <p>Also in the gridOptions, I mention:</p>
  
  <pre><code>onGridReady: function() {
                      gridOptions.api.sizeColumnsToFit();
                      gridOptions.api.refreshView();
                  }
  </code></pre>
  
  <p>Any idea what is the issue?</p>
