javascript - Submit multiple form values with AngularFire -

I try to understand how angular frames work. I am trying to save a first name and last name in my Firefox database. I successfully created a "first name" input and saved it in firebase. Now I try to add one last name input, but I can not understand how it works. Even what I do now:

HTML

  & lt; Section ng-controller = "premiercontrolleur" & gt; & Lt; Ul & gt; & Lt; Li ng-repeat = "customer in customer" & gt; & Lt; Input ng-model = "client.prenom" ng-change = "client. $ Save (client)" /> & Lt; Input NG-model = "client.nom" ng-change = "client. $ Save (client)" /> & Lt; Button ng-click = "client. $ Extract (client)" & gt; X & lt; / Button & gt; & Lt; / Li & gt; & Lt; / Ul & gt; & Lt; Form ng-submit = "addClient (newClientText)" & gt; & Lt; Input type = "text" placeholder = "prima" ng-model = "newClientText.prenom" /> & Lt; Input type = "text" placeholder = "no day family" ng-model = "newClientText.nom" /> & Lt; Button type = "submit" & gt; Ajoeter Le Client & lt; / Button & gt; & Lt; / Form & gt; & Lt; / Section & gt;   
 javascript  
  var app = angular Module ("chromefirebase", ["firebase"]); App.controller ("premiercontrolleur", function ($ radius, $ firebase) {var ref = new firebase ("https://mydirebaseurl.firebaseio.com/clients") var var == $ firebase (ref); client = sync . $ AsArray (); $ scope.addClient = function (prenom) {$ scope.clients. $ Add ({prenom: prenom, name: nom});}}); I received this error when I submitted:  
  Failed to read 'selection direction' property from 'HTMLInputElement': type of input element ('submit') does not support selection   
 
 
 You are not mixing the values ​​well, remember that Péren is an object with which Try the properties and names, then try:  
  $ scope.addClient = function (prenom) {$ scope.clients. $ Add ({prenom: prenom.prenom, nom: prenom.nom}); }
