GetColumnLabel name and run ajax function - google viz datatable

Question

Here I have google visualisation DataTable:

So i have this code:

function drawTroskovnik() {


  // Create and populate the data table.
  var JSONObject = $.ajax({
    url: 'getTroskovnik.php', // make this url point to the data file
    dataType: 'json',
    data:{id_akt:ajdi},
        async: false,
    type: 'POST',
    }).responseText;

  var data = new google.visualization.DataTable(JSONObject, 0.5);

for (var y = 0, maxrows = data.getNumberOfRows(); y < maxrows; y++) {
    for (var x = 1, maxcols = data.getNumberOfColumns(); x < maxcols; x++) {

      data.setValue(y, x, '<input id="costRedovi" class="form-control" value="'+data.getValue(y,x)+'">');
    }
} 
 for (var y = 0, maxrows = data.getNumberOfRows(); y < maxrows; y++) {

      data.setValue(y, 0, '<input class="span2 form-control" id="pocetak1" size="16" type="text" value="'+data.getValue(y,0)+'" readonly>');

} 


        data.addColumn('string', 'Kontrole');
        for (var y = 0, maxrows = data.getNumberOfRows(); y < maxrows; y++) {
        var mc= data.getNumberOfColumns()-1;
data.setValue(y, mc, '<a data-toggle="modal" data-target="#update" href="#" class="btn btn-success"><i class="fa fa-pencil"></i> Details</a>');

        }
new google.visualization.events.addListener(table, 'ready', function () {
        google.visualization.events.addListener(table.getChart(), 'select', function () {
            var selection = table.getChart().getSelection();
            //HOW TO GET LABEL of COLUMN an DATE from row so to use it in ajax submit
     $( "#costRedovi" ).focusout(function() {
            $.ajax({
            url: "update.php",
            type: "POST",
            async: true, 
            data: { columnName:HOW_to_get_column_name,datum:How_to_get_date_from_row_where_is_selected_cell?}, 
            dataType: "html",

            success: function(data) {
                console.log(data);   
            },  
        });
  })
                        }
        });
    });
  // Create and draw the visualization.
  visualization = new google.visualization.Table(document.getElementById('tpltroskovnik'));
  visualization.draw(data, {'allowHtml': true, cssClassNames: 'nn' }});
}

What I need to do? Now I have each cell value into input field, so I can change it. I want on .focusout to run .ajax function to update data in database, but to do this I need to get Column Label Name and date (as you can see on photo - date is a '0' position in row...)

How I can get Column Label Name and date for cell which is on focusout ?

Answer 1

It was very easy to solve this problem, so I get columnLabel on new better way:

for (var y = 0, maxrows = data.getNumberOfRows(); y < maxrows; y++) {
    for (var x = 1, maxcols = data.getNumberOfColumns(); x < maxcols; x++) {

      data.setValue(y, x, '<input id="costRedovi" kol="'+ data.getColumnLabel(x) +'" class="form-control" value="'+data.getValue(y,x)+'">');
    }
} 

so the solution was: data.getColumnLabel(x), now every input has attribute kol and now is easy to run ajax code when datatable is ready.
