They do go direct to government and do get a response in the House if sufficiently well supported, which triggers a debate even if policy is not changed.
No government would hold a referendum on that issue, they are only (to all intents and purposes - there are very rare exceptions) held when neither government or Parliament have the constitutional power to make a decision without one. You will see the government sometimes jump through hoops to avoid one as with anything involving the EU, but here the matter is clear.
