GPIO turns off automatically after some seconds

Hi Team,
I have a very simple project going on. Controlling 2 GPIO’s on/off;
I tried 2 different programs and the observation is same in both.
when i command a gpio to go high ; it goes high on button click and after uncertain time(seconds) it turns off.
I am attaching my both the programs.

1.: in html

function stop(channel)

	digitalWrite(2, 'LOW');
	status2 = "OFF";
	document.getElementById("status2").innerHTML = status2;
	}
	}
</script>

</body>
</html>

2: in js
singleButton({name:“Led On”, action:“digitalWrite”,
pin:“2”, value:“HIGH”})

Please help.
