Use PowerShell to call WMI EvtWmiInstanceSetItem?

In my WDF_WMI_INSTANCE_CONFIG structure I've defined the following callback functions for my provider:
- EvtWmiInstanceQueryInstance
- EvtWmiInstanceSetInstance
- EvtWmiInstanceSetItem
Using PowerShell I can use the Get-WmiObject and Get-CimInstance cmdlets to query my provider. My EvtWmiInstanceQueryInstance callback is called appropriately.
Using PowerShell I can use the Set-WmiInstance and Set-CimInstance cmdlets to set all instance data in my provider. My EvtWmiInstanceSetInstance callback is called appropriately.
How on Earth do I set a single item/property of my instance in my provider?
When I call set-wmiinstance -Path $path -Argument @{my_property=10} my EvtWmiInstanceSetItem callback is not called and instead my EvtWmiInstanceSetInstance callback is called.
I tried following the instructions below, but it seems to call my EvtWmiInstanceSetItem callback instead of my EvtWmiInstanceSetInstance callback.
