AEGP_RegisterListener in AE SDK 2017.1

Hi! I'm using AEGP_RegisterListener (in AEGP_RenderQueueMonitorSuite1) to register callbacks for a render in my AE plugin, but none of the functions I provide are getting called. My goal is to display an update dialog with a progress bar that updates during the render.

When searching for solutions, I found mention of "boilerplate" code that people added to get access to the Render Queue Monitor Suite, but I didn't have to do this to be able to call AEGP_RegisterListener. Is that boilerplate still required, and if so, how would I do it in 14.2 SDK?

Here's some relevant lines from my code (not the entire functions!):

// Structure to provide callback functions. These functions are defined in my code.

const AEGP_RQM_FunctionBlock1 g_renderFunctionBlock =

    { NBAERenderJobStarted,

      NBAERenderJobEnded,

      NBAERenderJobItemStarted,

      NBAERenderJobItemUpdated,

      NBAERenderJobItemEnded,

      NBAERenderJobItemReportLog };

err = SUITE_RENDERQUEUEMONITOR->AEGP_RegisterListener(PLUGIN->id(), (AEGP_RQM_Refcon)this, &g_renderFunctionBlock);

SUITE_RENDERQUEUE->AEGP_AddCompToRenderQueue(compH, path.c_str());

SUITE_RENDERQUEUE->AEGP_SetRenderQueueState(AEGP_RenderQueueState_RENDERING);

err = SUITE_RENDERQUEUEMONITOR->AEGP_DeregisterListener(PLUGIN->id(), (AEGP_RQM_Refcon)this);

The composition is rendering correctly. 'err' is 0 after RegisterListener and DeregisterListener. But I put breakpoints and prints in all the callback functions and none of them are hitting or printing.

What am I missing? I expected that during the blocking render (AEGP_SetRenderQueueState) the callbacks would execute, and from NBAERenderJobItemUpdated I would be able to increment the dialog's progress bar.
