Bash on Windows (10) doesn't recognize the installed version of node

I have installed Bash on my Windows 10 PC. Then I downloaded and installed the newest version of node (v6.10.2). Using the windows command line and typing "node -v" it tells me, that node v.6.10.2 is installed. Using the Bash command line and again typing "node-v" the output tells me that node v0.10.25 is installed.

How can I get Bash to recognize the new version of node?

Without the new version I cannot download any modules from npm.
