How to filter my data? (ng-grid)

Question

I think this is most likely very simple but I cannot find any clear documentation on how to add a filter outside of the \'filterText\' that is shown on their website. What I

I have found a way that updates instantly. Basically I hold a hidden set of all my data, and upon receiving new data or changing my filter - I apply this filter to the full data set and hand the grid the filtered version.

This lets me use comparators (i.e. age >= 50) in my filter, which is the purpose of this question.

// Full unfiltered data set
$scope.entries = []; // Updated and pushed to

$scope.gridOptions = {
    // The grids already filtered data set
    data: 'filteredEntries',
    enableColumnResize: false,
    multiSelect: false,
    enableSorting: false,
    selectedItems: $scope.selectedEntries,
}

 $scope.$on("updateEntries", function(data) {
     // My table is filled by socket pushes, this is where it is updated.
     $scope.updateFilters();
 }

 $scope.$on("newFilter", function(newFilter) {
     // This is where I update my filter
     $scope.updateFilters();
 }

 $scope.updateFilters = function() {
     // Filters the full set and hands the result to the grid. 
     $scope.filteredEntries = $filter('filter')($scope.entries, $scope.myFilter);
     $scope.$digest();
 }         

 // A modifiable limit, modify through newFilter so data is refiltered
 $scope.lowerLimit = 50;

 // My Filter
 $scope.myFilter = function(entry) { 
     if (entry < $scope.lowerLimit) {
        return false; 
     }
     return true;
 }
