1. Use ng-model to create the two-way data binding 1. 2. Create a directive in your angular module that will be applied to the same element and that depends on the ngModel controller module.directive('lowercase', function() { return {...

2 Way Data Binding The last item that I want to cover in this lesson is 2 way data binding. Angular provides 2 way data binding. Expressions are re-evaluated when their property changes. Angular keeps a track of the value stored in every expression. If the value of the expression changes...
