React Native Module Callback returns nothing

I am trying to get values from my java module to my js but my callback funtion returns nothing.

My module method:

@ReactMethod
public void foo(Integer stateNum, Callback func){
    final Integer num = stateNum;
    final Callback funcCallback = func;
    try{
        funcCallback.invoke(num);
    }catch (Exception e){}
}

Then I call it on my js:

showTest = () => {
    55,
    test.foo( (num) => {
        this.setState({ number1: num, number2: 200 })
    } );
}

So, when I run the showTest function, the state number1 is not updated but state number2 becomes 200, since I passed the value 200 directly from my js code. What is wrong with my code?

I was passing the argument at the wrong place and I also had forgoten to recompile the whole project. The application wasn't warning me about the arguments because I was simply reloading it instead of recompiling it.
