Integrating C Code with Simulink while running LaunchXL F28379D

I have been trying to add a C Code to a model which runs on LaunchXL F28379D. To test it, I created two files Source and Header. I called inside 'Simulation Target'. I have two functions running in the C Code. These are 'onee' and 'twoo'. I use a C Caller block to call the function 'onee' and When I try to run the model in external mode. I get the following error.

undefined first referenced
  symbol       in file     
 --------- ----------------
 _onee     Test_3.obj   

I think the function 'onee' is called inside the generated file C files, but the source and header files of my C Code are not propery mentioned. i.e I could not find #include "myfcn.h" in any of the generated C file.

I there any way to fix it?

I Solved my problem. Basically I had to add add .c and .h file to 'code generation' section as well. When I hit Run, Simulink generates code for LaunchXL thus it takes .c and .h files along with it.
