Why my event on export bootstrap-tables is not working?

I'm trying to make a function when the export start event happens, but I'm not able to catch this event. I'm trying alert() when on export-started.bs.table. Just doesn't work, so what is the event when I try export my table?

(I couldn't make an example of export in this code too, can someone help me put the button that downloads the file in excel?)

let arrData = [
      {
        'id': 0,
        'name': 'Item 0',
        'price': '$0'
      },
      {
        'id': 1,
        'name': 'Item 1',
        'price': '$1'
      },
      {
        'id': 2,
        'name': 'Item 2',
        'price': '$2'
      },
      {
        'id': 3,
        'name': 'Item 3',
        'price': '$3'
      },
      {
        'id': 4,
        'name': 'Item 4',
        'price': '$4'
      },
      {
        'id': 5,
        'name': 'Item 5',
        'price': '$5'
      }
    ]

$('#merged').bootstrapTable({
    data: arrData,
    exportTypes: ['csv','json','excel','doc','txt','sql','xml'],
    exportDataType: 'all',
    columns: [{
                title: "id",
                align: 'center',
                valign: 'middle',
                field: "id"
            },{
                title: "name",
                align: 'center',
                valign: 'middle',
                field: "name"
            },{
                title: "price",
                align: 'center',
                valign: 'middle',
                field: "price"
            }]
});

Solution

That should work. You must enter the event in the table configuration.

onExportStarted: function (arg1, arg2) { alert('hi'); },

let arrData = [
      {
        'id': 0,
        'name': 'Item 0',
        'price': '$0'
      },
      {
        'id': 1,
        'name': 'Item 1',
        'price': '$1'
      },
      {
        'id': 2,
        'name': 'Item 2',
        'price': '$2'
      },
      {
        'id': 3,
        'name': 'Item 3',
        'price': '$3'
      },
      {
        'id': 4,
        'name': 'Item 4',
        'price': '$4'
      },
      {
        'id': 5,
        'name': 'Item 5',
        'price': '$5'
      }
    ]

$('#merged').bootstrapTable({
    data: arrData,
    exportTypes: ['csv','json','excel','doc','txt','sql','xml'],
    exportDataType: 'all',
    showExport: true,
    onExportStarted: function (arg1, arg2) { alert('hi'); },
    columns: [{
                title: "id",
                align: 'center',
                valign: 'middle',
                field: "id"
            },{
                title: "name",
                align: 'center',
                valign: 'middle',
                field: "name"
            },{
                title: "price",
                align: 'center',
                valign: 'middle',
                field: "price"
            }]
});
