I am trying to build a 4×16 decoder with only 4 decoder.. I've just made this. Basically each decoder has 2 enable signals. Is it correct?

Yes, it is correct as shown. However, I don't think there is a real world decode or demux part that has two pairs of complimentary enable pins with all of the internal logic to make them work. To build your schematic you will have to add some inverters to some of the device select/enable inputs.
