Display Variable with UI Text

I created a new UI>Text object and named it ‘Player1Stamina’. This text is supposed to constantly display the value of the variable ‘stamina’ found in the script ‘player1Movement’.

The problem is I cannot get the text displayed during Play to say anything other than the line of placeholder text I put in the text field on the ‘Player1Stamina’ which is currently ‘Player 1 Stamina’.

using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class player1Movement : MonoBehaviour {

	public Text Player1Stamina;
	private int stamina;
	int maxStamina;
	int staminaRecharge;
	bool staminaRecharging;
	bool canMove;

	void Start () 
	{
		maxStamina = 100;
		stamina = 100;
		SetStaminaText ();
		staminaRecharge = 2;
		staminaRecharging = true;
		canMove = true;
	}

	void Update () 
	{
		if (staminaRecharging = true && stamina < maxStamina) 
		{
			stamina += staminaRecharge;
			SetStaminaText ();
		}
		if (Input.GetKey ("space")) 
		{
			stamina -= (staminaRecharge * 5);
			SetStaminaText ();
		}
            if (Input.GetKey ("z"))
            {
                    stamina += (staminaRecharge);
			SetStaminaText ();
            }
	}
	void SetStaminaText ()
	{
		Player1Stamina.text = "Stamina: ";
	}	
}

I think it misses to add the variable stamina to the Player1Stamina.text. It should look like this:

Player1Stamina.text = "Stamina: " + stamina;

I must be doing something else wrong in addition to that @TheMrAngel, because the UI text on screen for Player1Stamina does not change unless I edit the text box in it’s Text component.
