Trigger search as soon as user is done with editing

1

How to implement Search bar.Once user inputs the String data , I want to trigger a function .
basic looking for binding the input field with some event call back like doneEditing and then firing the required function.

You can use onblur event which will be triggered once the user moves the cursor out of the input field. If you are using a mobile, then you can use ng-enter function on the input field.

<input type="search" placeholder="Search here" ng-enter="searchString()"/>
