Using if function block in MATLAB Simulink

I have created the following block diagram on Matlab Simulink. It should give OUT1=1 OUT2=0 when INPUT>=0 and OUT1=0 OUT2=1 when INPUT<0. But it does not give the expected results. What is the reason for that. Any advice to make it work correctly would be appreciated.

You should use a Merge block with the outputs of the "if" and "else" subsystems, and then look at the signal coming out of that block.
