How can I change block parameters in simulink using block path in app designer?

I want to change block parameters (by refrrencing the block's path) in simulink using app designer.

In order to make .exe file I used SimulationInput object as the below code:

simInp = Simulink.SimulationInput('test_model');

I can't use simInp.setBlockParameter because of this error:

and I couldn't use set_param because it dosen't accept SimulationInput object an an input.

Here is the full code:

function startupFcn(app)
            start_simulink;
 end

% Button pushed function: simulateButton
function simulateButtonPushed(app, event)
    try
        simInp = Simulink.SimulationInput('test_model');
        simInp = simInp.setBlockParameter("test_model/Gain",'Gain',num2str(app.kkEditField.Value));
%                 set_param('test_model/Gain','Gain',num2str(app.kkEditField.Value));
        simInp = simulink.compiler.configureForDeployment(simInp);
        simOut = sim(simInp);

        t = simOut.tout;
        y = simOut.yout{1}.Values.Data;
        plot(app.UIAxes,t,y);
    catch ME
        errordlg(ME.message);
    end

end

Would you please help me about the solution?
