I use a file parameter in hda, and when i recook the hda, the callback script don't execute.
the parameter(file path) don't change, but the file changed, i need the callback script to execute.
Is there a method to execute the script?
Thanks.

Update: If i call HEU_Parameters.SetStringToParameter(parameter_name, parameter_value), change the file path, the hda will recook, but the script still don't execute, and when i open the hda in houdini(HoudiniEngine->Debug->Open Scene in Houdini), the script was executed.
