Faucet Side

How I can solve the side spray on my kitchen faucet?
I broke the handle on the side spray on my kitchen faucet. "I can Side Spray buy and install? Or should I buy a new faucet to fix? If so, is there an easy installation or should I call a plumber? Part 2 Spray side I can buy new come with all this, or having the "cord" or any other to go with him?
just get the handle, close the valve and unscrew the broken pipe, introducing the new has to push and turn the spring because they do not .. water again,,,,
