Change attribute in visu following a knx object

[Andrea Becagli]

Does not seem to be working, I probably got something wrong 

I pasted this in in my javascript custom:

Code:

$(function() {
  if (typeof grp != 'object') {
    return;
  }

  grp.listen('32/1/22', function(object, state) {
    $('.dis_da_totale').toggleClass('el-disabled', object.value == false);
  });
});

 
pasted this in Custom CSS:

Code:

.el-disabled {
  opacity: 0.5;
}
.el-disabled,
.el-disabled * {
  pointer-events: none !important;
}

and I used dis_da_totale as an additional class for the button is that correct, or am I missing something?
