While Digvijay totalled seven-under-par 281 for the tournament, Bhullar and Gangjee finished a stroke behind on 282. The fourth Indian in the fray, Gaurav Ghei (72), finished tied 57th with a total of four-under-par 284.
Chinese Taipei star Lin Wen-tang battled through inclement weather to lift the inaugural title after carding a blistering eight-under-par 64 in the final round.
He produced a four-day winning total of 23-under-par 265 for a commanding five-stroke triumph over Korean teenager Noh Seung-yul who hit a 71.
Digvijay, a 10th tee starter, was off the blocks with a birdie before picking up another stroke on the 13th. An 18th-hole birdie completed a flawless front nine leaving him three-under at the turn. On the back nine, he had birdies on the second and sixth holes but a dropped shot on the par-4 ninth spoilt his card.
