Unable to get response with Retrofit Coroutine api call

I am trying to get response into live data from api, but request is not getting called with this code.

class AuthActivityViewModel : ViewModel() {

    var authResp: LiveData<ObjAuthResp> = MutableLiveData()

    val repository = BaseRepository()

    fun login(username: String, password: String) {
        authResp = liveData(Dispatchers.IO) {
          val resp = repository.login(username, password)
            emit(resp)
        }
    }
}

but it works with this code.

class AuthActivityViewModel : ViewModel() {

    val repository = BaseRepository()

    var authResp = liveData(Dispatchers.IO) {
        val resp = repository.login(username, password)
            emit(resp)
    }    

}

API service

@POST("profile/pub/auth/login")
suspend fun login(@Body authReqBody : ObjAuthReqBody): ObjAuthResp

BaseRepository

open class BaseRepository {

    suspend fun login(username:String,password:String) = service.login(ObjAuthReqBody( username, password))   
}

Calling from activity

   btn_login.setOnClickListener {
    viewModel.login(edt_username.text.toString(), 
    edt_password.text.toString())
    }

Answering my own question,

the problem was in line authResp = liveData(Dispatchers.IO) {... this was creating new LiveData while the old observers where observing the initial var authResp: LiveData<ObjAuthResp> = MutableLiveData(). So, as there is no Observers listening to the newly created LiveData the call is not even being made.

This code is working 

  var authResp = MutableLiveData<ObjAuthResp>()

 fun login(username: String, password: String) {
        viewModelScope.launch {
            withContext(Dispatchers.IO) {
                val resp = repository.login(username, password)
                authResp.postValue( resp)

            }
        }
    }
