Using Approval and Disapproval for Device

Question

I am fetching record from database and printing it on table. See the Image:

For Device-permission column I want to use Button which will show Disapproved (means device is approved )if value is "true" and OnClick on the button i want to call a function which will update the value "false " against the IMEI in to database (means now the device become disappoved to use ).. In the same way if the value is false I want to show a button which will display Approve means on click of it I want to call a function to update the value true at the place of false against that IMEI in database . The code is:

<script type="text/javascript">
/**
 * This code declares your class and saves an object "blogentry" to the table on StackMob.
 * StackMob will create the table for you automatically based on your JSON.
 */
 $(document).ready(function() {
            result();
            function result() {

            var device = StackMob.Model.extend({ schemaName: 'device' });
            var mydevice = new device({ });
                    var q = new StackMob.Collection.Query();
                    q.equals('device_org', 1);
                    q.setRange(0,9).orderDesc('lastmoddate');

                    mydevice.query(q, {
                        success: function(modal) {
                            //After StackMob returns "Bill Watterson", print out the result
                            var array = modal.toJSON();
                             // console.debug(array);
                             //$('#data').html(array[0].user_name);
                             var val = array[0].lastmoddate;
                             $('#last_mod_date').attr('value', val);


                                var key;
                                var count = 0;
                                for(key in array) {
                                     if(array.hasOwnProperty(key)) {
                                      count ++;
                                     }
                                 }
                                 //alert(count);
