selector for input with a dynamic value and span with dynamic value jquery

In my project i have a table that populate data into. In this table i have a dynamic header with span(x axis) and dynamic value with input(y axis). They are both populated dynamically depending on user insert. In between them are input checkbox. The main goal is to find the value of a certain span and find the value of a certain input then locate the checkbox where they meet then check the checkbox.

Here is what i have tried

var $td = $('#flooring').find('span:contains('+value.floorno+')').find('input[value='+ value.material +']');
$('#flooringtable tr:not(:eq(0)) td').find(':eq('+$td.index()+')').find('input[type="checkbox"]').prop("checked", true);

UPDATE

This is the default table since i add the input dynamically it is not here

<table id="flooring">
    <tr>
        <td><strong><p>Flooring</p></strong>
        </td>

var newRow = $('<tr/>');
    var i = 0;
    newRow.append('<td ><input type="checkbox" class="materialsothersdeleteflagfloor" name="materialsothersdeleteflag[]" />Other(Specify)<span id="materialsfloor_inputtext_othersspan"><input type="text" value = "' + value.material + '" name="" class="" id="materialsfloor_inputtext_others' + i + '"></td>');
    for (i; i < numberCheckBox; i++) {
        newRow.append('<td><input type="checkbox" class="materialsfloor' + i + ' checkboxmatfloor" name="materialsflooring[]" /></td>');
        //$('.checkboxmatfloor[value="' + value.floorno + " " + value.material + '"]').prop("checked", true);
    }
