Looks more like a media stunt by the Election commission to save its face. If they are real serious then they should pay security researchers to find a bug in the EVMs, Like bug bounties with real money prizes. As a computer programmer I find it hard to believe that EVMs cannot be hacked.
Even better political parties which are claiming about machines fallacy should show some better evidence than 'Only because of machines we lost' bullshit.
The burden of proof (or at least of showing good evidence) rests on those deciding to deploy the equipment. If the best response they can offer is to assert "that did not happen", the system is not ready for deployment.
