Info Message not Dissapearing

[Coder2]

How should I remove the info message from the portal once I call it from the spUTIL in client script, tried many ways, the latest is at the bottom. I dont want to do it through Backend, only frontend.  Is there any way to add a timer on infomessage so it goes away on the portal from the frontend, again NO BACKEND?

<div>
<!-- your widget template -->
  <h1>Hello Worls</h1>
  <button type="button" class="btn btn-primary" ng-click="func()">Primary</button>
</div>

api.controller=function($scope, $location, $rootScope, spUtil, $timeout, spModal) {
	/* widget controller */
	var c = this;
	//var msg = spUtil.addInfoMessage('HEELO WORLS');

	$scope.func = function(){
		//c.data.action = 'boom';
		//console.log('func called');
		$scope.page.gs.clearMessages();
		c.server.update().then(function(response){
			c.server.refresh();
		})
	}
};

(function() {
	/* populate the 'data' object */
	/* e.g., data.table = $sp.getValue('table'); */
	//gs.flushMessages()
	//gs.addInfoMessage("Hello");
	gs.flushMessages();
	if(input && input.action == 'boom'){
		
		console.log('called')
		console.log("cased")
		gs.flushMessages();
	}
	

})();
