Need to get checkboxes checked in Angular if-statement

I have two lists of IDs that I need to check against. If they match then that check-box should be checked. I'm new to angularJs so please help me width this. My code looks like this now. allMedia is a object with many values. mediaIdFromSpecifikLead is just a list with int id.

<tr ng-repeat="media in allMedia">
    <div ng-repeat="mediaFromLead in mediaIdFromSpecificLead">
        <div ng-if="media.Id == mediaFromLead ">
            <td>
                <input type="checkbox" ng-checked="true" />
            </td>
        </div>
        <div ng-if="media.Id != mediaFromLead ">
            <td>
                <input type="checkbox" ng-checked="false" />
            </td>
        </div>
    </div>
</tr>

With this code it even shows TWO check-boxes (one checked and one empty) so not even that works so I have probably done this totally wrong.
