CRM Online: SubGrid OnLoad not triggering when parent form initially loads?

I'm attempting to perform some dynamic filtering upon a SubGrid in an entity's Form. I have followed the example as described on MSDN (https://msdn.microsoft.com/en-us/library/dn932126.aspx#BKMK_subgridAddOnLoad) to register a custom function to SubGrid's OnLoad event. That registration code works, however, while my OnLoad function triggers during pagination events, it does not when the Form is initially loaded. Below is the script I am currently using:

var testFunc = function () { console.log("This is a test"); }
function onLoadForm() {
    // get sub-grid by name
    var subGrid = Xrm.Page.getControl("SubGridName");
    subGrid.addOnLoad(testFunc); 
}

What am I doing wrong? Or does the subgrid OnLoad not trigger when a form is loaded? If not, how do I get my function executed once the grid has data?

Thanks!
