How can this element button be clicked using protractor?

I'm trying to select this button using protractor:

<button tabindex="-1" type="button" class="btn btn-default pull-left" ng-click="$arrowAction(-1, 0)">

 <i class="glyphicon glyphicon-chevron-up">
 </i>

</button>

the only unique element in this is ng-click="$arrowAction(-1, 0)"

Nothing I have tried works:

element(by.css("//button[@ng-click='$arrowAction(-1, 0)']")).click();
