Why working permanent alias in hyper terminal doesn't work in vs-code bash terminal?

I'm on Windows 10 machine and I just installed VS-Code to use instead of Atom. I tried to use permanent alias in VS-Code Bash Terminal which I had created & was working fine in Hyper Terminal, but it doesn't work in VS-Code terminal. Why is that & How can I fix it ?

I have

alias mongod="/c/Program\ files/MongoDB/Server/4.0/bin/mongod.exe"
alias mongo="/c/Program\ Files/MongoDB/Server/4.0/bin/mongo.exe"

in my '.bash_profile' file
