	if(document.getElementsByTagName("iframe").length > 0){
		var iframe = document.getElementsByTagName("iframe")[0].contentWindow;
		iframe.postMessage('{"event":"command","func":"' + 'pauseVideo' +   '","args":""}', '*');
	}
}

$scope.$on('$ionicView.beforeLeave', function(){
	$scope.pauseVideo();
});
