AngularJS ng-bind issue

Question

I am working on angular application. I need to bind two model variable using ng-bind and two variables from two different scope (One from parent and other from child scope). Is that possible?

Here is the code what I tried:

<input tabindex="2" id="{{ClientAC}}" ng-model="a.ClientAC" 
       ng-blur="clientFocusout()" ng-keydown="clientKeyDown($event)" />
