Is it possible to open the default block dialog after a custom OpenFcn callback?

I'd like to use the OpenFcn callback of a simulink block to run a script and then after the script is complete open the standard block dialog like normal. So far in the documentation I've only found references that any change to the OpenFcn callback will override the default behavior but no mention of how to pro grammatically open the default block dialog afterwards.
I've have created a workaround by placing code in the script which sets the OpenFcn callback of the current block to an empty string and then reopens it, followed by setting it back to calling the script. (see example below) This just feels like a really bad way to accomplish this and wondered if anyone knew of a better solution.
% Portion of code from my script that opens the default dialog
set_param(gcbh, 'OpenFcn', '')
open_system(gcbh)
set_param(gcb, 'OpenFcn', 'exampleScript;');
Thanks.

In the OpenFcn of the block, run your script and the call open_system to open block dialog.
% In OpenFcn of block
exampleScript;
open_system(gcbh, 'parameter');
I think it should work. (I dont have access to Matlab to try this now)

I updated the answer. You need to call open_system with 'parameter' argument to open the block dialog.
% In OpenFcn of block
exampleScript;
open_system(gcbh, 'parameter');
