Android : Java Spinner Calculator not working

I have created two spinners; a meal type spinner (e.g. Breakfast) and a food spinner (e.g. Toast). Once a food type is selected in the spinner, the user enters a number in an EditText, and a calculation will be done to calculate the total calories (PSEUDO: CALORIES * WEIGHT ENTERED). However my calculator doesn't seem to be doing anything and I'm not sure why as I am getting no errors.

public class MainActivity3 extends ActionBarActivity {

private List<Food> planlist =new ArrayList <Food>();
private ArrayAdapter<Food> planAdapter1;

private planOnClickListener myClickListener = new planOnClickListener();

public Spinner catspinner, planspinner;

protected void onCreate(Bundle mbfSplash) {
    super.onCreate(mbfSplash);
    setContentView(R.layout.addmeal);

    chooseCategory();
    chooseBreakfast();
    chooseLunch();
    chooseDinner();
    chooseSnack();
}

public void chooseCategory() {

    catspinner =(Spinner) findViewById(R.id.catspinner);
    ArrayAdapter<CharSequence> catAdapter = ArrayAdapter.createFromResource(this, R.array.ducategory, android.R.layout.simple_spinner_item);
    catAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    catspinner.setAdapter(catAdapter);
    catspinner.setOnItemSelectedListener(new planOnClickListener());
}

private void chooseBreakfast() {
    planspinner =(Spinner) findViewById(R.id.planspinner);
    planlist.clear();
    planlist.add(new Food("Porridge-35g/140cal",4));
    planlist.add(new Food("Coffee-10g/10cal",1));
