Input value doesn't display. How is that possible?

Question

This must be something utterly stupid that I\'ve done or am doing, but I have an input with a value attribute that simply isn\'t being displayed:

Answer 1

Mine was related to AngularJS

I was trying to put both an HTML Value and an ng-Model, thinking that the ng-Model would default to the Value, because I was too lazy to add the Model to the $scope in the Controller...

So the answer was to assign that default value to the $scope.variable in the controller.
