BaseController with Generic Entity and Model

Question

I created a controller with generic TEntity and TModel so that i will not have to repeat common actions like save/delete for each entity. I just want to ask if this is a good or a bad practice?

public class BaseController<TEntity, TModel> : Controller
        where TEntity : BaseEntity
        where TModel : BaseModel
    {
        private readonly IMapper _mapper;
        private readonly IRepository<TEntity> _repository;
        private readonly IUnitOfWork _uow;
        public BaseController(
            IMapper mapper,
            IRepository<TEntity> repository,
            IUnitOfWork uow)
        {
            _mapper = mapper;
            _repository = repository;
            _uow = uow;
        }
        public IActionResult Index()
        {
            return View();
        }

        [HttpPost]
        public async Task<IActionResult> Save(TModel model)
        {
            if (!ModelState.IsValid)
                return Json(ModelState);

            try
            {
                if (model.Id > 0)
                {
                    var record = await _repository.GetAsync((int)model.Id);

                    if (record == null)
                        return Json(new NotFound());

                    _mapper.Map(model, record);
                }
                else
                {
                    var entity = _mapper.Map<TEntity>(model);
                    _repository.Add(entity);
                }

                await _uow.CompleteAsync();

                return Json(new Success("Record saved successfuly!"));
            }
            catch (Exception ex)
            {
                return Json(new InternalError(ex.Message));
            }
        }

        [HttpPost]
        public async Task<IActionResult> Delete(int id)
        {
            try
            {
                var record = await _repository.GetAsync(id);

                if (record == null)
                    return Json(new NotFound());

                record.IsDeleted = true;
                await _uow.CompleteAsync();

                return Json(new Success("Record successfully deleted."));
            }
            catch (Exception ex)
            {
                return Json(new InternalError(ex.Message));
            }
        }
