How to use a MutableLiveData Object in my xml?

Question

I have an object that will fill some fields in my xml, but a mutablelivedata return a T value and I can't use the T properties. What I need to do to use the T object in my xml?

I don't want to create a mutablelivedata for each object member.

Sorry for my bad english..

class ExampleFragment: Fragment() {
    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
        val viewModel = ViewModelProviders.of(this).get(MyVm::class.java)

        val binding = DataBindingUtil.inflate<FragmentExampleBinding>(
            inflater,
            R.layout.fragment_house,
            container,
            false
        )

        binding.myVm = viewModel
        binding.lifecycleOwner = this

        return binding.root
    }
}

class MyVm: ViewModel(){
    val house: MutableLiveData<House> by lazy { MutableLiveData<House>().apply{ value = 
        House().apply{ 
            door = "First door"
            window = "My window"
        }
    } }

    val thing: MutableLiveData<String> by lazy { MutableLiveData<String>().apply{ value = "something" } }
}

class House(){
    var door: String = ""
    var window: String = ""
}

This code is correcty! A tried run and worked, I thounght it didn't work because the android studio didn't show the attributes when press ctrl + space.
