Having issues with home search widget code

[DevtoSME]

I've been following the articles as written on how to fix this code issue for my widget but there's noting previewing in the section to show. is there something wrong with the code?

this for HTML

<h1 class="text-center text-4x m-b-lg sp-tagline-color" ng-bind="data.greeting"></h1>

and for 

client script:

function() {

  /* widget controller */

  var c = this;

  c.data.greeting = 'Hi ' + g_userID.user.first_name; 

}

Hi @DevtoSME ,

Try this :

function($scope) {
var c = this;
c.welcome = ''HI" + $scope.user.first_name + "!";
}
