我的程序没有更新mongodb

我是新的MVC。我正在做一个程序，在mongodb中编辑现有记录。我的程序没有更新记录。

这是编辑方法:

[HttpPost]
public async Task<ActionResult> Edit(BioCardModel model)
{
    await _bioCardServices.UpdateBioCard( model.cardId ,model);
    return RedirectToAction("Index");
} 

这个方法更新数据库中的记录

public async Task UpdateBioCard(Guid value, [FromBody]BioCardModel card)
{
    var db = ConnectToMongo();
    var collection = db.GetCollection<BioCardModel>(_collection);
    var filter = Builders<BioCardModel>.Filter.Eq("cardId", value);
    var update = Builders<BioCardModel>.Update
        .Set(b => b.name, card.name)
        .Set(b => b.firstName, card.firstName)
        .Set(b => b.lastName, card.lastName)
        .Set(b => b.title, card.title)
        .Set(b => b.lifeSpan, card.lifeSpan)
        .Set(b => b.bio, card.bio)
        .Set(b => b.bio, card.anecdote)
        .Set(b => b.imageFront, card.imageFront)
        .Set(b => b.imageBack, card.imageBack);
    await collection.UpdateOneAsync(filter, update);
}

我的视图是一个用记录数据填充的简单表单。
