MOSFET half bridge driver not working
IN pin should not be pulled high continuously , this driver is a bootstrap driver , which means it needs to recharge the bootstrap capacitor through the low side mosfet when the high side mosfet is off.

buttom line , IN pin should be PWM from 0 to around 95% but never to 100%. 

if you want 100% , ( for some applications you do ) there is solutions like adding  a charge pump ... etc 

check out this app note from Texas instruments Providing Continuous Gate Drive Using a Charge 

EDIT:

After checking the datasheet it seems you have another mistake , that is powering the IR2104 from 5v , the IR2104 accepts 3.3v and 5v and 12v logic inputs at IN and SD , but its supply (aka VCC ) should be above between 10v to 20v. the IGBT voltage can be 5v no problem .
