I'm trying to align two buttons to ad input field but I end up messing everything every single time.
I've already aligned an input field to a single button, but I'm not able to add a second button.
This is the html (I'm using some angularjs):
<div class="row">
<div class="col-lg-12">
<form class="form" ng-submit="vm.reCreateTree(ricercaSecondario)" ng-init="aggiornaRicercaPratica()">
<div class="input-group">
<input type="text" ng-model="vm.cercaSecondario" class="form-control" placeholder="{{getTestoPlaceholderRicerca(ricercaPraticaSecondario)}}" required="required" ng-disabled="disabilitaRicercaSecondaria()">
<div class="input-group-btn">
<button class="btn btn-default" type="submit"><i class="fa fa-search"></i></button>
<button class="btn btn-default" type="submit"
tooltip="Espandi filtri di ricerca" tooltip-placement="bottom"
ng-click="toggleRicerca()" ng-show='user.ambitoSelezionato.nome == "Clienti-Polizze"'>
<i ng-class="{'fa fa-caret-up': showEspandiRicerca, 'fa fa-caret-down': !showEspandiRicerca}"></i>
</button>
</div>
</div>
</form>
</div>
</div>
This is a screenshot of the result:

As you can see the two button are not in the same line as the input field and they are also uneven (speaking about dimensions)...
Any help?!
UPDATE: updated the code (thanks to Mukesh Ram) but the buttons still have two different sizes..
