placeOrderEx function not working

When I try to use the 'ibtws' class in MATLAB R2014a to place order from the Interactive Brokers (IB) Trader Workstation , for instance if I am trying to run the following example function 'placeOrderEx', Nothing showed up on my IB Order Blotte or Trade Station.

My code is as follows, how can I fix this? Thanks

IB = ibtws('',7496);
eventNames = {'errMsg','orderStatus'};
for i = 1:length(eventNames)
  registerevent(IB.Handle,{eventNames{i},...
  @(varargin)ibExampleOrderEventHandler(varargin{:})})
end 

f = findobj('Tag','IBOrderBlotter');
if isempty(f)
  f = figure('Tag','IBOrderBlotter','MenuBar','none',...
    'NumberTitle','off','Name','IB Order Blotter');
  pos = get(f,'Position');
  set(f,'Position',[pos(1) pos(2) 687 335])
  colnames = {'Status' 'Filled' 'Remaining' 'Avg Fill Price' 'Id' ...
    'Parent Id','Last Fill Price','Client Id','Why Held'};
  data = cell(15,9);
  uitable(f,'Data',data,'RowName',[],'ColumnName',colnames,...
        'Position',[10 30 677 300],'Tag','OrderDataTable');
  uicontrol('Style','text','Position',[10 5 592 20],...
        'Tag','IBOrderMessage');
  uicontrol('Style','pushbutton','String','Close',...
            'Callback','evalin(''base'',''close(IB);...
              close(findobj(''''Tag'''',''''IBOrderBlotter''''));'')',...
              'Position',[607 5 80 20]);
end

IB.Handle.reqAllOpenOrders

ibContract = IB.Handle.createContract;
ibContract.symbol = '700';
ibContract.secType = 'STK';
ibContract.exchange = 'SEHK';
ibContract.currency = 'HKD';

ibOrder = IB.Handle.createOrder;
ibOrder.action = 'BUY';
ibOrder.totalQuantity = 10000;
ibOrder.orderType = 'MKT';

orderId = 10;
placeOrderEx(IB.Handle,orderId,ibContract,ibOrder)

You may wish to try the cross-platform IB-Matlab product, which is Java-based (not ActiveX):

You won't encounter such problems with IB-Matlab, it is very reliable and user-friendly.
