Data store memory can not set initial value using set_param

I make Model.slx and open this file.

And put a Data Store Memory.

MATLAB Command window

listMask = find_system('Model','LookUnderMasks','all','BlockType','DataStoreMemory');

get_param( listMask, 'Initialvalue' ) Ans= '0'

get param is OK(I can read initial value on DataStoreMemory). But

set_param(listMask(1),'InitialValue','test')

=>Invalid Simulink object specifier

I can not set initial value ('test') using set_param

Please tell me how to set the initial value using set_param.

use this

set_param(listMask{1},'InitialValue','test')

listMask(1) and listMask{1} are different.
