MATLAB: How to install select callback function in STF

Question

I was trying to declare model reference compliance in STF. This is what i did to install select callback:

rtwgensettings.Version = '1';

rtwgensettings.SelectCallback = 'custom_select_callback_handler(hDlg, hSrc)';
slConfigUISetVal(hDlg, hSrc, 'ModelReferenceCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ModelReferenceCompliant', false);
slConfigUISetVal(hDlg, hSrc, 'ParMdlRefBuildCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ParMdlRefBuildCompliant', false);

When I try to load the STF, I get following error:

Warning: The following error occurred processing the System Target File '':

Undefined function or variable 'hDlg'.

What am I missing?

Thanks.

The code:

slConfigUISetVal(hDlg, hSrc, 'ModelReferenceCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ModelReferenceCompliant', false);
slConfigUISetVal(hDlg, hSrc, 'ParMdlRefBuildCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ParMdlRefBuildCompliant', false);

Should be defined in a separate MATLAB file named custom_select_callback_handler.m that should be present on the MATLAB path:

function custom_select_callback_handler(hDlg, hSrc)
slConfigUISetVal(hDlg, hSrc, 'ModelReferenceCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ModelReferenceCompliant', false);
slConfigUISetVal(hDlg, hSrc, 'ParMdlRefBuildCompliant', 'on');
slConfigUISetEnabled(hDlg, hSrc, 'ParMdlRefBuildCompliant', false);
