Replying to Pop out of bindings at bad times

i have public enemies with salomon 912ti's on em for 2 years now, din is at 7.5 and i have made sure that the toepiece is down on the tounge of my boot, but when i spin sevens or nines i torque out of the one ski all the time. this really sucks alot cause i leave one ski sitting on the lip of the jump and land on a boot, which isnt fun. why would this be happening, i even tried to crank the din up to 11 and tried a 1080 the other day and got hurt pretty bad, so if theres any advice id apprec.

I love to ski so much.
