I'm failing to control some leds.

I am trying to control some "DotStar" LED strips from adafruit with a raspberry pi. I am using a level shifter to go from the pi's 3 volts to 5 volts for the leds. The component in the diagram is not the level shifter but I used it to hold its place as it has the same amount of pins.

This is the level converter: https://www.adafruit.com/images/product-files/1787/1787AHC125.pdf
