How to get a bail for 498A and 313 IPC

I am residing abroad since March 2015. My wife filed 498A and 313 case on 2nd May 2015 in Kolkata police station and they filed a charge sheet on 30th August 2016 after 1.4 years. In FIR and charge sheet, only my name is present as accussed. My wife's parents is supporting me, so their names are not present in witness in charge sheet. She has a boyfriend who is helping her and doing these thing. The important witnesses are two doctor names who gave her a gastric medicine PAN D and she is using that report for 313 case as suggest by her boyfriend, who is also a witness. I have a original medical report of that doctor to proof this false 313 case. Till date, I did not receive any summon from court. Now, I want to come India to face a trial and prove myself as innocent. I want to apply regular bail. Please suggest what are the possibilities to get a bail and what document as proof, which I can produce to get a regular bail. Her father is also ready to come in court, if it is required in bail. Please suggest the possibilities.
