Objects seemingly not being instantiated after touch.

I've been digging around and trying to find the answer to this question but found nothing. I'm trying to create a simple clicker game but got stuck at the very start... which is not very good. What I'm trying to do is after a touch give the player money (currently just adding +1$) and spawning in a text object saying "+1$". Seems like the object does not appear. I also made an "animation" which I'm not sure if it's well made. Both classes:

 public class MoneyTap : MonoBehaviour {

 public GameObject money;
 private Text moneyText;
 public long moneyAmount = 0;
 public GameObject tapText;
 private Vector2 tempPos;
 private Vector3 fullPos;

 void Start () {
     moneyText = money.GetComponent<Text> ();
 }
 
 // Update is called once per frame
 void Update ()
 {
     moneyText.text = moneyAmount + "$";

     if (Input.touchCount > 0) {
         if (Input.GetTouch (0).phase == TouchPhase.Began) {

             tempPos = Input.GetTouch(0).position;
             fullPos = new Vector3 (tempPos.x, tempPos.y, 0);

             
             RaycastHit2D hitInfo = Physics2D.Raycast (Camera.main.ScreenToWorldPoint (Input.GetTouch(0).position), Vector2.zero);
             // RaycastHit2D can be either true or null, but has an implicit conversion to bool, so we can use it like this
             if (hitInfo) {
                 moneyAmount++;;
                 Instantiate(tapText, fullPos, Quaternion.identity);
             }
         }
     }
 }
 }

And:

 public class TapTextMovement : MonoBehaviour {

 private int frameCount = 0;
 private float temp;
 public int modifier = 0;

 // Use this for initialization
 void Start () {

 }
 
 // Update is called once per frame
 void Update () {
     if (frameCount < 40) {
         temp = this.transform.position.y + 1F * modifier;

         this.transform.position = new Vector3(this.transform.position.x, temp, this.transform.position.z);
     } else if (frameCount < 50) {
         temp = this.transform.position.y + 0.5F * modifier;

         this.transform.position = new Vector3(this.transform.position.x, temp, this.transform.position.z);
     } else if (frameCount < 55) {
         temp = this.transform.position.y + 0.3F * modifier;

         this.transform.position = new Vector3(this.transform.position.x, temp, this.transform.position.z);
     } else if (frameCount < 60) {
         temp = this.transform.position.y + 0.15F * modifier;

         this.transform.position = new Vector3(this.transform.position.x, temp, this.transform.position.z);
     } else {
         Object.Destroy (this);
     }
     frameCount++;
 }
 }

I am a bit new to Unity so every bit of help would be appreciated! Thanks!
