How to handle grid events

[vangundy]

Could you provide an example of handling the onRowClick and onSelectionChanged events of the data grid? I tried this:
this.gridOptions = {
onRowClick: (e) => { this.handleRowClick(e); },
onSelectionChanged: (e) => { this.handleSelectionChanged(e); },
bindingOptions: {
dataSource: "collection",
}}
...but I can't get the events to fire when I click on the grid. TY
