title: Angularjs: greater than filter with ng-repeat
body: <p>I'm applying a greater than filter to a ng-repeat tag. I wrote the following custom filter function:</p>
  
  <pre><code>$scope.priceRangeFilter = function (location) {
      return location.price &gt;= $scope.minPrice;
  };
  </code></pre>
  
  <p>and I use it in the following HTML code:</p>
  
  <pre><code>&lt;div ng-repeat="m in map.markers | filter:priceRangeFilter"&gt;
  </code></pre>
  
  <p>What is the best way to trigger a refresh of the ng-repeat tag when $scope.minPrice is updated?</p>
