I have an array of objects and I am using an ng-repeat to iterate over them, which is easy. The array looks something like this:
ng-repeat
$scope.steps =
In case this is an option for you, if you put your data into object form it works the way I think you're hoping for:
$scope.steps = { companyName: true, businessType: true, physicalAddress: true };
Here's a fiddle of this: http://jsfiddle.net/zMjVp/
