Angular to disable ng-repeat checkbox based on value

I like to explain my problem clearly

I have a list of checkbox displayed using ng-repeat, now i need to disable some checkbox based on specific value checkbox is checked.

checkbox display code

<div class="checkbox">
     <label ng-repeat="specific in specifications">
          <input ng-click="onClick(specific, newObject[specific])" id="specifications_chk" value="" ng-model="newObject[specific]" type="checkbox">
          
     </label>
</div>

Here am using ng-click function to disable checkbox.

This is my controller code:

$scope.onClick = function(sp, checked){
        if(sp == 'Sofa_Cleaning' && checked === true){
            angular.element(document.getElementById('specifications_chk'))[0].disabled = true;
        }

        if(sp == 'Sofa_Cleaning' && checked === false){
            angular.element(document.getElementById('specifications_chk'))[0].disabled = false;
        }

    };

html view:

in controller code am able disable only first value (IndepthHomeCleaning), so how can i disable Room_Cleaning, Kitchen_Cleaning, and Carpet_cleaning when Sofa_Cleaning is checked

Am i stuck with this, Help will be really appreciated
