如何初始化片段中的綁定屬性以使雙向數據綁定工作

所以我在做一個項目，我完全迷路了。我已經看到了如何使用textview進行數據綁定，但是有人要求我使用EditText視圖進行雙向數據綁定。到目前為止，我都是帶著它來的。

The XML File.

    </androidx.constraintlayout.widget.ConstraintLayout>
</layout>

我被告知要實現它的一個片段，它應該工作。但我不知道怎么做。這是碎片

class ShoeDetailsFragment : Fragment() {

    private val viewModel: ActivityViewModel by activityViewModels()

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {


        val binding: FragmentShoeDetailsBinding = DataBindingUtil.inflate(
            inflater,
            R.layout.fragment_shoe_details,
            container, false
        )



        //initializing the button and clearing the views once canceled
        binding.cancelButton.setOnClickListener { v: View ->
            v.findNavController().navigateUp()

            binding.shoeName.text.clear()
            binding.shoeSize.text.clear()
            binding.companyName.text.clear()
            binding.shoeDescription.text.clear()

        }
        //initializing the button and saving the info to transfer to the shoeList
        binding.saveeButton.setOnClickListener { v: View ->
            v.findNavController().navigateUp()

            val name = shoe_name.text.toString()
            val size = shoe_size.text.toString()
            val brand = company_name.text.toString()
            val details = shoe_description.text.toString()
            viewModel.addShoe(name, size, brand, details)
        }

        return binding.root
    }
}

我愿意接受任何初始化綁定屬性的想法，這樣我就可以在布局和片段中使用它。還是我看錯了？

另外，XML文件在這個片段中表示
