Multiple enemy array in LibGDX

I am trying to make a multiple enemy array, where every 30 secods a new bullet comes from a random point. And if the bullet is clicked it should disapear and a pop like an explosion should appear. And if the bullet hits the ball then the ball pops. so the bullet should change to a different sprite or texture. same with the ball pop.

But all that happens is the bullet if touched pops and nothing else happens. And if modified then the bullet keeps flashing as the update is way too much.

I have added COMMENTS in the code to explain more on the issues.

below is the code. if more code is needed i will provide.

Thank you

public class GameRenderer {

private GameWorld myWorld;
private OrthographicCamera cam;
private ShapeRenderer shapeRenderer;

// Game Objects

private ScrollHandler scroller;

private Bullet bullet1;
private BulletPop bPop;

private Array<Bullet> bullets;

    // This is for the delay of the bullet coming one by one every 30 seconds.
/** The time of the last shot fired, we set it to the current time in nano when the object is first created */
double lastShot = TimeUtils.nanoTime();
  /** Convert 30 seconds into nano seconds, so 30,000 milli = 30 seconds */
 double shotFreq = TimeUtils.millisToNanos(30000);

           // this is where i am trying to make the bullets come one by one, and if removed via the onClick() then bPop animation 
           // should play but does not???

         /* Very important to set the last shot to now, or it will mess up and go full auto */
         lastShot = TimeUtils.nanoTime();
      }

    // End SpriteBatch
    batcher.end();
