Dynamic label in grid weboptions

[robinhodemorais]

Hello, I have a dbgrid and put a label next to the buttons with the number of grid records, but this information will change every time the user performs one, to put a label I managed to do it like this

function pagingBar.boxready(sender, width, height, eOpts)
{

  this.add({
     xtype:'label',
     html: '10.358'
  });
  
    this.add({
     text: 'Pedido',
     handler: function() {
       top.ajaxRequest(sender,'novopedido', [])
     }
  });
  
  }

But how can I make it dynamic?
because in this same function I use it to include buttons
