OnTriggerEnter2d unity not working

I'm new on using Unity, and I'm trying to use a sprite as a collision trigger. But my OnTriggerEnter2d won't trigger. Here are the infos:

main character info main character info

collision sprite used as trigger info sprite use as trigger

And code for the newPlatformRow script attached to the main character

using UnityEngine;
using System.Collections;

public class NewPlatformRow : MonoBehaviour {

    private float leftPlatformX = -12f; //de unde incepe platforma din stanga
    private float rightPlatformX = 3.123f; // de unde incepe platforma din dreapta
    private float rowDistance = -5f; //distanta dintre randurile de platforme

    private float leftPlatformWidth; //acestea vor fi calculate random pt fiecare rand nou
    private float rightPlatformWidth;





    // Use this for initialization
    void Start ()
    {
        //Debug.Log("why wont you work ;_;");

    }

    // Update is called once per frame
    void Update () {
        //Debug.Log("why wont you work ;_;");
    }


    void OnTriggerEnter2d(Collider2D other)
    {

        Debug.Log("why wont you work ;_;");

        if (other.gameObject.CompareTag("newPlatformRow"))
        {

            Vector3 newLeftPlaformPosition;
            Vector3 newRightPlaformPosition;

            var leftPlatform = GameObject.Find("LeftWallPlatform");
            var rightPlatform = GameObject.Find("RightWallPlatform");

            newLeftPlaformPosition = new Vector3(leftPlatform.transform.position.x, leftPlatform.transform.position.y + rowDistance, leftPlatform.transform.position.z);
            newRightPlaformPosition = new Vector3(rightPlatform.transform.position.x, rightPlatform.transform.position.y + rowDistance, rightPlatform.transform.position.z);

            Transform leftPlatformTransform = leftPlatform.transform;
            Transform rightPlatformTransform = rightPlatform.transform;

            Transform newLeftPlatform = Instantiate(leftPlatformTransform, newLeftPlaformPosition, leftPlatformTransform.rotation) as Transform;
            Transform newRightPlatform = Instantiate(rightPlatformTransform, newLeftPlaformPosition, rightPlatformTransform.rotation) as Transform;

            newLeftPlatform.parent = leftPlatformTransform.parent;
            newRightPlatform.parent = rightPlatformTransform.parent;

        }
    }
}

Not that the: Debug.Log("why wont you work ;_;"); it's never called

full scene info: enter image description here

I really can't figure out what am I doing wrong. Thanks

You are not checking isTrigger checkbox in material component.

It seems that you have misspelled void OnTriggerEnter2d(Collider2D other). It should actually be OnTriggerEnter2D. Note that capital D here. All the names for triggers and colliders like OnMouseDown() work the same way - they must have the exact same name, case sensitive.
