Invoke Function by Ui Button

Good Evening,
I would like to invoke a function after you press the button, I tried every way but it does not work. Do you have any idea?

This is my script

public void ResumeGame()

{
	anim.SetTrigger ("NoPausa");
	Invoke ("ResumeGAME",0.84f);
}

void ResumeGAME ()
{
	PausePanel.SetActive (false);
	Time.timeScale = 1.0f;
	paused = false;
}

After several tests, it seems that fails to invoke the function, I tried but it does not work the same with coroutines
