      initComponent: function () {
  
          var me = this;
  
          Ext.apply(this, {
              frame: true,
              bodyPadding: 7,
              border: 0,
              items: [{
                  xtype: 'textfield',
                  fieldLabel: 'First Name',
                  name: 'contact_attr'
              }, {
                  xtype: 'textfield',
                  fieldLabel: 'Last Name',
                  name: 'contact_attr'
              }],
              buttons: [{
                  text: 'Send',
                  handler: function () {
                      me.getForm().submit({
                          url: '/salary/public/auth/',
                          standardSubmit: true,
                          method: 'POST'
                      });
                  }
              }]
          });
