AngularJS div background color with ngStyle

One of my div s is observing a background color variable with ngStyle. Anytime I change the the value, I get an error. Please see below, I think I am more or less consistent with this example https://docs.angularjs.org/api/ng/directive/ngStyle

<div class="item item-divider" ng-style="scoreColor"><b>Rate</b>&nbsp;{{score}}</div>
<input type="range" name="rate" min="1" max="10" value="5" step="1" ng-model="score" ng-change="changeScoreColor(score)"/> 

$scope.changeScoreColor = function(score){
    $scope.scoreColor = "{background-color:" + colorFromScore(score) + ";}";
};

The ng-style expects an object with styles i.e.:

$scope.changeScoreColor = function(score){
    $scope.scoreColor = {'background-color': colorFromScore(score) };
};

You're passing a string instead of object hence the error.

Here's what documentation says about expected ng-style argument:

Expression which evals to an object whose keys are CSS style names and values are corresponding values for those CSS keys.
