Dynamically enable pinning

[Bhimisetty]

Hi,
I would like to enable the pinning dynamically for the grid. I tried by setting the property to true dynamically as follows.
$scope.gridOptions.enablePinning=true;
but the expected result not came.
Here is the small plunker "http://plnkr.co/edit/MucJQAvskBrAjrXfHdIb?p=preview" i worked.
Plz let me know what the issue?

Many of the grid features aren't dynamic - they are set on grid creation and not updated when you change the options. I would expect this to be another example, there is a description in #1819

Closing as ng-grid is deprecated.
