shouldSideBeRendered method does not work when registering the block

[seferlian]

So I can't make the block invisible in water.

    @Override
    @SideOnly(Side.CLIENT)
    public boolean shouldSideBeRendered(IBlockState state, IBlockAccess blockAccess, BlockPos pos, EnumFacing side) {
        BlockPos neighbourPos = pos.offset(side);
        IBlockState neighbourState = blockAccess.getBlockState(neighbourPos);
        if (neighbourState.getBlock() == Blocks.WATER || neighbourState.getBlock() == state.getBlock()) {
            return false;
        }
        return super.shouldSideBeRendered(state, blockAccess, pos, side);
    }

Also, the onEntityCollidedWithBlock event does not work, and most likely, the onEntityWalking event does not work either.
