AngularJS Custom checkbox filter

Ive been trying to add some checkboxes to filter out my <md-card> and <md-table> that populate data on ng-repeat.

This is what my checkbox looks like:

<ul>
    <li ng-repeat="tech in technologyArray">
        <label>
            <input type="checkbox" ng-model="tech.on">
        </label>
    </li>
</ul>

This is what my custom filter looks like:

$scope.technologyArray = [{
                containerId: "7519183",
                on: false
            }, {
                containerId: "8031029",
                on: false
            }];

 .filter('customFilter', function() {
    return function(input, techs) {

        if(!techs || techs.length === 0) return input;
        var out = [];
        angular.forEach(input, function(item) {
            angular.forEach(techs, function(tech) {

                if (item[0].containerId === tech.containerId) {
                    out.push(item);
                }
            });
        });
        return out;
    }

And this is my JSON:

 {
    "1": {
        "accountId": "17467569***",
        "containerId": "7519***3",
        "usageContext": ["web"],
        "tag": 1,
        "trigger": 1,
        "variable": 4,
        "account_name": "Account2"
    },
    "2": {
        "accountId": "***",
        "containerId": "***",
        "usageContext": ["web"],
        "account_name": "Account2",
        "missing_live": true
    },
    "3": {
        "accountId": "***",
        "containerId": "***",
        "usageContext": ["web"],
        "tag": 2,
        "trigger": 1,
        "variable": 1,
        "account_name": "Account 1"
    },
    "4": {
        "accountId": "***",
        "containerId": "***",
        "usageContext": ["web"],
        "tag": 0,
        "trigger": 0,
        "variable": 1,
        "account_name": "GTMdocx"
    },
    "5": {
        "accountId": "***",
        "containerId": "***",
        "usageContext": ["web"],
        "account_name": "GTMdocx",
        "missing_live": true
    },
    "6": {
        "accountId": "21281***2",
        "containerId": "8038***",
        "usageContext": ["web"],
        "tag": 0,
        "trigger": 0,
        "variable": 0,
        "account_name": "Account3"
    }
}

Also this line in my custom filter is not right, because i have to add item[0] wich is not right because inside item we have multiple lines of JSON objects:

 if (item[0].containerId === tech.containerId) {
                    out.push(item);
                }

Hope someone could help me, thanks!

This is my NG-repeat of <md-card> and <table> if needed:

        <md-toolbar>
            <div class="md-toolbar-tools" ng-repeat="container in account | limitTo: 1">
