How to change the value of title using AngularJS?

Hello,

I don’t know if I did it wrong, it allowed me to go to the next one though, but on the localhost browser section it doesn’t show the contents that are saved under the $scope.title. The<h1>{{ title }}</h1> would print out {{ title }}, is that suppose to happen?

the same goes when I do the section in Hello AngularJS II for the $scope.promo. the <h2>{{ promo }}</h2> doesn’t show the contents that are placed under the $scope.promo and just shows {{ promo }}. I copied and paste what they said to put so yeah…

Is this suppose to happen using AngularJS?
