Problem regarding Simulink model & GUI interfacing

How can I interface a Simulink model to a GUI in MATLAB 2010a. I am using 'sim()' in command window & I am getting the result, but when I paste the same command inside a callback function of a push-button in GUI. There is no response. What should I do? Thank You.

When sim() is called inside a function, the results are saved into the workspace of the function, and will disappear when the function returns. When sim() is called from the command line or from the menus, then the results are saved into the base workspace, where they will stay until cleared or overwritten.
