How to programatically update many CAN Pack blocks

Hello, I'm currently using VNT with Matlab 2011b, I have an issue related with the CAN Pack block, similar to the issue related in this post:

http://www.mathworks.com/matlabcentral/answers/92755-why-do-my-can-pack-unpack-blocks-not-update-when-i-load-programatically-a-new-dbc-file-in-simulink-7?s_tid=answers_rc1-1_p1

I'm trying to apply the script apply_CAN_block(gcb) sequentially to update programatically different CAN Pack blocks, however, is not working as intended, when the scripts is called many times it fails to update all the different CAN Packs. It seems to be a problem with synchronization.

Below you can find the code I'm trying to use with the .p function

function name = configure(sys,i) 
x = 30; 
y = 30; 
w = 300; 
h = 300; 
offset = 300; 

BUS = 'HS1'; 
CAN_DBC_Path = 'C:\Users\edorant1\Documents\MATLAB\CAN_DBC\P552_R05\'; 
Msg = 'ABS_BrkBst_Data_HS1'; 
pos = [x y+h/4 x+w y+h*.75]; 
tic 
name=strcat('/In',num2str(i)); 
add_block('MdlBuilderLib/CAN Pack',[sys name],'Position',pos); 
set_param([sys name],'DataFormat','CANdb specified signals'); 
set_param([sys name],'CANdbFile',[CAN_DBC_Path,BUS,'.dbc']); 
set_param([sys name],'MsgList',Msg); 
apply_CAN_block([sys name]); 
pause(0.01); 
name = [sys name]; 
toc 
end

cuenta.a = []; 
cuenta.b = []; 
cuenta.c = []; 
cuenta.d = []; 
cuenta.e = []; 
cuenta.f = []; 
cuenta.g = []; 
cuenta.h = []; 
cuenta.i = []; 
cuenta.j = []; 
cuenta.k = []; 
cuenta.l = []; 
cuenta.m = []; 
cuenta.n = []; 
cuenta.o = []; 
cuenta.p = []; 
cuenta.q = []; 
cuenta.r = []; 
cuenta.s = []; 
cuenta.t = []; 
cuenta.u = []; 

name = cellfun(@(i) configure(sys,i),fieldnames(cuenta),'UniformOutput', false );

please let me know any idea to solve this problem .
