title: NativeScript App Alert is still showing "About to Register at the end of lesson 3 in tutorial
body: <p>After completing the 3rd lesson "Application Logic" of the NativeScript Groceries tutorial, I am not getting the correct "Alert" message described as coded in login.component.ts. Instead I am still getting the "About to register......." Alert that was discussed earlier in the lessson. I should see a different message as shown in the signup function snippet.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code> signUp() {
        this.userService.register(this.user)
        .subscribe(
          () =&gt; {
            alert("Your account was successfully created.");
            this.toggleDisplay();
          },
          () =&gt; alert("Unfortunately we were unable to create your account.")
        );
      }</code></pre>
  </div>
  </div>
