Create custom type

I want to create new value for the columns.type format. For instance if I define a column

$('#' + idTable).dataTable( {
    data: content,
    columns: [{
        "data": "rate",
        "type": "percentage",
    }]
});

Every time I set type to percentage, I want it to :

• call a specific render function for rendering the value (for instance multiply the value by 100 and append " %")
• call specific function for searching and sorting.
• why not automatically set specific option like searchable = false for percentage value.

How to archieve it ?
