How to fix this circuit (IR 2184) ?

Hi all, I refer to this website at here . This circuit should give a complementary square waveform (R1 square wave & R2 inverted square wave). However, I did get a good square wave across R2 but R1 did not get any square wave. Does anyone know how to fix this? I have attached my LT spice below for convenience. Please put in 1 folder to run it. Thank you and have a good day!!

Connect VS to Ground. At this point short VCC and VB. (remove diode)
This is not how the IC was intended to work but .......... it should get you going.

What is the correct way? Can help to simulate in LT SPICE from my file ?

Doesn't the datasheet show you a typical circuit for using the IC?
The circuit is not how the IC was designed. This is a strange way to use the circuit.
If you really want a signal across R1 and the inverse across R2 then do Post #2. (not in data sheet) You must not use the boot strap function.
