                         id : &quot;id&quot;,
                         fields: {
                             id: { editable: false, type: 'number'},
                             name: { editable: true, type : &quot;string&quot; },
                             unique_url: { editable: true , type: 'string'},
                             image_url : { editable: true, type : &quot;string&quot; },
                             title: {type : &quot;string&quot;, validation: {
                                                  required: true,
                                                  validateTitle: function (input) {
                                                      console.log(&quot;I am inside validation&quot;,input.val());
                                                      if (input.val().length &gt; 5) {
                                                         input.attr(&quot;data-validateTitle-msg&quot;, &quot;Max length exceeded 5 characters only&quot;);
                                                         return false;
                                                      }    
  
                                                      return true;
                                                  }
                                              }
                                              },
                             body: { editable: true, type : &quot;string&quot;,validation: { max: 90, required: true, message : &quot;Maximum characters should be 90&quot;} },
                             adaccount_id: { editable: false, type: 'number'}
                         }
