How to make a text update by 1 everytime you press space.

Questions & Answers

Right now my code to make the score go up by 1 is:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class Score : MonoBehaviour {

    public Text scoreText;
    public int scoreIncreasesBy = 1;

	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
		if (Input.GetAxis("Jump") == 1)
        {

            scoreText.text = "Score:" + scoreIncreasesBy.ToString();
        }
	}
}

But the score only goes up when I first press space. It is meant to go up whenever you press space.
Please help.
