Was playing around with a previous example... I'd like to generate the columns for the grid based on what is returned from a call to the server. 

 

For example, in the example below 

$scope.columns would not actually be hardcoded in the success() function, but rather be assigned to an object which has been returned in response

Resolved -made k-ng-delay dependent on "columns", removed $scope.columns and gridOptions.columns
