How to run the examples?

After installing with `haste-inst install`,
I run: `hastec --with-js=lib/stubs.js example/simple/simple.hs --out=example/simple/main.js` from the root of the project
And then open the file in chrome. 
And when I type in the input box, the texts doesn't change.

Does it depend on some fixed version of ghc? I use `7.6.3`
