I made a custom armor model, now how do I make the model stay in the item? for example, the jetpack mekanism mod.

You would need to make an identical model in json/obj and make the item have that model just as any other item. And before you ask - yes, there is a way to reuse your ModelBiped code and no, I won't be supporting it or explaining it as it is not the use case for it. Make a model for your item in something like BlockBench and export it to both json(item model) and java(armor model).

I don't think that the jetpack model has many (if any) moving parts so you can just use the JSON in the armor model I believe.

public net.minecraft.client.model.ModelBiped getArmorModel(EntityLivingBase entityLiving, ItemStack itemStack, EntityEquipmentSlot armorSlot, net.minecraft.client.model.ModelBiped _default)

The custom model for the armor must be an instance of ModelBiped. Unless you want to invent a way to convert a IBakedModel into a ModelBiped this is impossible with this method. Even if you go around this method and use events to render a IBakedModel you will have a nightmare trying to animate parts of it(you can't split the model into parts because the item needs to be a single model obviously and armor parts are rotated differently).

Thats what I was suggesting

The jetpack model doesn't have any moving parts, just 2 variants.

Point taken though
