Thank you Alex. I had a requirement to automatically set the date field to something other than the current date. I was able to accomplish this through utilizing the Edit event from the grid.
//For example:
.Events(e => e.Edit("onEdit"))
//Here's the javascript function that is called when the popup editor launches.
function onEdit(e) {
var someDate = "1/26/2020";
e.model.set('DateField', someDate );
}
