Restarting level on Android not working

Im using this code to restart the level when i press the back key on my phone but nothing is happening…

	void Update()
	{
		if(Input.GetMouseButtonDown(0))
			jump = true;


		if (Input.GetKeyDown(KeyCode.Escape)) 
			{
				Application.LoadLevel(Application.loadedLevel);

						return;
			}

Found the solution, its GetKey instead of GetKeyDown
