Question

In my form I have a client field. I need that when the user presses the delete or Return (delete) key, a method that I have in my controller is triggered, how can I capture if one of these keys was triggered?

I am using Angularjs

this is my input:

<input placeholder="Digite as iniciais para fazer a pesquisa." class="md-input label-fixed" ng-model="registro2.razao"/>

Hello try adding the directive to your input:

ng-keydown="teclaPress($evento)"

and in your controller adds the function keyboard

  $scope.teclaPress = function(ObjKey) {
    // teu codigo por exemplo debug
    console.log(ObjKey.key); // Tecla que clicaste
  }
