I have a datatable with a Search functionality having 2 input boxes - one to input minimum age and one to input maximum age. The datatable does not have a column age but rather a column DOB in date format. Now I need to search max/min age based on the DOB. For example, I will input 10 in box minimum age and 15 in box maximum age and based on the matching DOB it should return the specific rows. (So far, it works if I have to search the age as an integer when it is already in a column.) Any idea how I can achieve this.

What I have tried:

so far I tried below code but showing no desired results. I know I am missing a lot of logic here.
    function( dateString,settings, data, dataIndex ) {
        var min = parseInt( $('#min').val(), 10 );
        var max = parseInt( $('#max').val(), 10 );
        var age = parseFloat( data[5] ) || 0; // use data for the age column
        var today = new Date();
        var birthDate = new Date(dateString);
        // var age = today.getFullYear() - birthDate.getFullYear();
        var m = today.getMonth() - birthDate.getMonth();
        if ( m < 0 || (m === 0 && today.getDate() < birthDate.getDate()) || ( isNaN( min ) && isNaN( max ) ) ||
             ( isNaN( min ) && age <= max ) ||
             ( min <= age   && isNaN( max ) ) ||
             ( min <= age   && age <= max ) )
            return true;
        return false;
		    var table = $('#example').DataTable();
    // Event listener to the two range filtering inputs to redraw on input
    $('#min, #max').keyup( function() {
    } );

You're overcomplicating this.

You get the current date.
Adjust the year datepart to your min and max range but keep the rest of the current date unchanged.*
Test your table of dates (DOB field) to determine if it's between these dates (inclusive).

(Modify the date object directly - you can make two of them so it's extra easy)
