I have a list in a table and put a column to display the amount of clicks when clicking.

But how could I mend the value coming from the bank and save.

Would it be by ajax? If so, how would I do it??

Below the code to get an idea.

.wis-numbers>span {
    margin-right: -1px;
    padding: 7px 12px;
    border: 1px solid #E0E0E0;
    float: left;
    font-weight: 500
}
.wis-numbers>span>i {
    line-height: 100%;
    vertical-align: top;
    position: relative;
    top: 3px;
    font-size: 15px;
    margin-right: 2px
}
.wis-numbers>span.active {
    color: #4CAF50
}
.zmdi-favorite-outline:before{
content:'\f15e'
}
.zmdi-favorite:before{content:'\f15f'}

<div class="wis-numbers">                                            
                                                        <span class="active"><i class="zmdi zmdi-favorite"></i> 78</span>
                                                    </div>

You can place your page that will receive the requests of ajax for whenever it is requested to update the value for one more and print the updated value.

The SQL command would be this:

UPDATE suaTabela SET suaColuna = suaColuna + 1;

Here is an example of ajax code:

let contador = document.getElementById('contador'); //elemento que vai ser clicado.
let contagem = document.getElementById('contagem'); //elemento que mostra a contagem.

contador.addEventListener('click', function(){
  let ajax = new XMLHttpRequest();
  let url = "SuaPaginaAqui";
  ajax.open("POST", url, true);
  ajax.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
  ajax.send();
  ajax.onreadystatechange = function() {
    if (ajax.readyState == 4 && ajax.status == 200) {
      contagem.innerHTML = ajax.responseText;
    }
  }
});
