Can we add multiple JS in events

It should actually work:

But it should be better to group the both function in the js code - function defintion

$scope.app.myNewFunction= function(){
$scope.setSequnece("sequence1");
//or $scope.app.setSequnece("sequence1");
// if defintion in app
$sope.B1();
}

and then call app.myNewFunction(); in UI
