JSON response always returns zero for int value

I call HTTP request with retrofit library and get results from an API. I configure log in retrofit library so i could see what's going on. The response is a simple primitive integer type. The problem is that it always returns zero. Response class(LoginModel) is also a classic class with one setter and one getter for integer type.

public class LoginModel {

  @SerializedName("result")
  private int result;

  public void setResult(int result){
    this.result = result;
  }

  public int getResult(){
    return result;
  }
}

Below image is my log which you can see i got response 10 but when i log getResult in onResponse function, it prints always zero.

Log.i("BODY : ", String.valueOf(response.body().getResult()));

I can't figure out whats wrong. I appreciate any help. thanks

UPDATE: full code of calling API

Call<LoginModel> isSended = apiService.sendCode(phoneNumber);
            isSended.enqueue(new Callback<LoginModel>() {
                @Override
                public void onResponse(Call<LoginModel> call, Response<LoginModel> response) {
                    Log.i("BODY : ", String.valueOf(response.body().getResult()));
                    if (!response.isSuccessful()) {
                        Toast.makeText(context, context.getResources().getString(R.string.errorServer), Toast.LENGTH_LONG).show();
                        dismissProgressBarDialog();
                        return;
                    }
                    myTimer = new MyTimer(SECOND_TIME, 1000);
                    views.reactionActivationPress(response.body().getResult());
                }

                @Override
                public void onFailure(Call<LoginModel> call, Throwable t) {
                    Log.i(Constant.NETWORK_LOG, "sendCode : " + t.toString());
                    dismissProgressBarDialog();
                    Toast.makeText(MyApplication.getContext(), "Server Problem", Toast.LENGTH_LONG).show();
                }
            });
