Top down zelda-like knockback working only on y axis

Tried using these (not together) in the OnTriggerEnterCollider2D, both work only on the y axis, not on the x. What am I doing wrong?

                Vector2 directionVector = other.transform.position - transform.position;
                Rigidbody2D body = other.GetComponent<Rigidbody2D>();
                if (body != null)
                    float forceMagnitude = 0.8f;
                    ForceMode2D mode = ForceMode2D.Impulse;
                    body.AddForce(directionVector * forceMagnitude, mode);
Vector3 direction = (other.transform.position - transform.position).normalized;
                    body = other.GetComponent<Rigidbody2D>();
                    body.AddForce(direction * 10);

You could use iTween! Use this code:

void OnColliderEnter2D(collision col) {
if(col.gameObject.tag == "yourTagHere") {

iTween.MoveTo(GameObject target, Vector3 position, float timeSpan);
