Fix event listener leaking

[Palakkgoyal]

This PR closes #1142
Fixed the memory leaking. The event listener was not remove correctly from the useEffect as they have give name of the constant instead of the function and I think window.addEventListenere doesn't return anything. So, the constant become undefined.
