Not able to call script within a script

I am working with solaris 5.9 Sparc and I write one script(test.ksh) which calls the other script(demo.ksh) but when I am executing the test.ksh,it is not calling the demo.ksh script.

I am calling demo.ksh file in test.ksh as given below--

Please tell me what is going wrong ???

alias command creates an alias and it doesn't actually run any commands.

Does nothing except creates an alias (but only inside the script). Add

at the end and it prints "something".
