Replying to Tyrolia mojo bindings

Ive got the mojo bindings and i got new boots this year..and supposedly they werent mounted correctly on the ski for that particular boot...but i ski'd them anyway..and i had no problem throwin huge stuff..and hittin rails and all that good stuff until now...now they pop off like crazy and are real loose on my ski..the guy at my local shop said i should just get them remounted to my skis and they should be fine...but i think they might fall apart..idk what to do//i might just buy some new bindings..
