below my FootballAdapter.kt where I have used databinding

import android.os.Build

import android.view.LayoutInflater

import yodgorbekkomilov.edgar.footballapp.ui.FootballViewModel


    class FootballAdapter :
        RecyclerView.Adapter<FootballAdapter.ViewHolder>() {
    
       private lateinit var footballList: List<FootballResponse>
    
        fun updatePostList(footballList: List<FootballResponse>) {
            this.footballList = footballList
            notifyDataSetChanged()
        }
    
        override fun onCreateViewHolder(
            parent: ViewGroup,
            viewType: Int
        ): FootballAdapter.ViewHolder {
            val binding: FootballItemBinding = DataBindingUtil.inflate(
                LayoutInflater.from(parent.context),
                R.layout.football_item,
                parent,
                false
            )
    
            return ViewHolder(binding)
        }
    
        override fun getItemCount(): Int {
            return footballList.size
        }
    
    
        @RequiresApi(Build.VERSION_CODES.O)
        override fun onBindViewHolder(holder: FootballAdapter.ViewHolder, position: Int) {
            holder.bind(footballList[position])
    
    
        }
    
    
        class ViewHolder(private val binding: FootballItemBinding) : RecyclerView.ViewHolder(binding.root) {
    
    
            private val viewModel = FootballViewModel()
    
            fun bind(model: FootballResponse) {
    
                viewModel.bind(model)
                binding.viewModel = viewModel
    
    
    
    
    
            }
    
        }
    }

below FootballViewModel.kt

    private val clubName = MutableLiveData<String>()

    private val countryName = MutableLiveData<String>()
    private val clubValue = MutableLiveData<String>()
    private val clubImage = MutableLiveData<String>()
    private val europeanTitle = MutableLiveData<String>()

    fun bind(football: FootballResponse){
        clubName.value= football[0].name
        countryName.value = football[1].country
        clubValue.value = football[2].value.toString()
        clubImage.value = football[3].image
        europeanTitle.value = football[4].europeanTitles.toString()

    }

    fun getClubName():MutableLiveData<String>{
        return clubName
    }

    fun getCountryName():MutableLiveData<String>{
        return countryName
    }

    fun getClubValue():MutableLiveData<String>{
        return clubValue
    }

    fun getImage():MutableLiveData<String> {
 return clubImage

    }


    fun getEuropeanTitle():MutableLiveData<String> {
        return europeanTitle

    }
}

}

what I have tried 1.invalidate cache restart 2. I have checked xml carefully it did not solve problem 3. tried following After migration to androidX: Databinding problem (Android Studio 4) and ActivityMainBindingImpl cannot be found in this one as well it did not solve my problem

I want to know where I am making mistake
