                            model.$setValidity('usernameExists', false);

HTML

<input type="text" class="role-textbox" id="rolename" name="rolename" required unique-role send-value="roledetails.name"  ng-model="roledetails.name" placeholder="{{::'placeholder.addRole.name'|translate}}">

Controller add a property in the object 

scope:{
 sendValue: '='
}

the scope.sendValue in the directive will bind to the text value in your controller

You basically want to know how to send data to your custom directive? If that is the case here is an example, on your input you should have something like:

<input unique-role data="customData">

Where customData is a property defined inside you controller that is responsible for the current view. The property should be attached to your controller through $scope.

Now inside the directive:

scope: {
    data: '='
}

And you would have access inside the directive through the scope to data. Keep in mind that there are 3 ways of binding data to directives, that is one of the ways, you can read more about it here.
