Nested directives with transclusion - angularjs

Question

I have a set of form directives in which duplicate code can be extracted into a separate directive.
I know that I can use transclusion, but have not been able to identify any technique that allows this (element cloning or passing functions). Tutorials on pluralsight, sitepoint and few other describe extraction into a directive inside the current directive, but I have not been able to apply them to my use case.
Brief Synopsis:-
Two sample directives
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3 col-xl-2">
<div class="form-group">
<label ng-show="visible">Input:
<input ng-model="person.name" type="text" required>
</label>
<p ng-show="!visible"> {{person.name}} </p>
</div>
</div>
And
<div class="col-xs-12 col-sm-6 col-md-4 col-lg-3 col-xl-2">
<div class="form-group">
<label ng-show="visible">Input:
<select> <option value="volvo">Volvo</option> .... </select>
</label>
<p ng-show="!visible"> {{person.name}} </p>
</div>
</div>
I wish to condense them into directives like
<my-input-box ng-model="person.name" required></my-input-box>
<my-select-box options = "person.options"></my-select-box>
where my-input-box template is
<my-wrapper-box><input ng-model="person.name" type="text" required></my-wrapper-box>
and my-select-box template is
<my-wrapper-box><select>......</select></my-wrapper-box>

How do I extract the wrapper box so that 2-way binding is maintained with the ng-model and overriding attributes like required, bootstrap classes, validation regex, etc. in either the my-wrapper-box or the transcluded HTML element?
Many thanks to all who have read the question. I look forward to your suggestions.

Plunker.
I've added the following to myInputBox directive:
controller: function(){},
bindToController: true,
controllerAs: 'ctrl',
and changed the html to
<my-wrapper-box>
<input type="text" ng-required="reqd" ng-model="ctrl.value" />
</my-wrapper-box>
