Editable html table (PHP, MySQL) - doesn't save changes in database

Question

For my final project, i'm trying to make my html tables editable by users, with updating data in MySQL. I've found in web a few js scripts for such case but no one works as needed. My result - editable table with correct data, but new entered data are not saved in the sql table. What I'm missing?

Data for table:

 require("../includes/config.php"); 

    $doctors = CS50::query("SELECT id, name, mob, hours FROM doctors");

    render("doctors_form.php", ["title" => "Doctors", "doctors" => $doctors]);

This is "saveInlineEdit" script I've used

<script>
    function saveInlineEdit(editableObj,column,id) {
    // no change change made then return false
    if($(editableObj).attr('data-old_value') === editableObj.innerHTML)
    return false;
    // send ajax to update value
    $(editableObj).css("background","#FFF url(loader.gif) no-repeat right");
    $.ajax({
        url: "saveInlineEdit.php",
        cache: false,
        data:'column='+column+'&value='+editableObj.innerHTML+'&id='+id,
        success: function(response)  {
            console.log(response);
            // set updated value as old value
            $(editableObj).attr('data-old_value',editableObj.innerHTML);
            $(editableObj).css("background","#FDFDFD");         
        }          
   });
}
</script>

This is html table (js script is in this file on the top):

<table>
        <tr>
            <th>Name</th>
            <th>Mob</th>
            <th>Hours</th>
        </tr>

<?php foreach ($doctors as $doctors): ?>

    <tr>
        <td contenteditable="true" data-old_value="<?= $doctors["name"]?>"
        onBlur="saveInlineEdit(this,'name','<?=$doctors["id"]?>')"><?=$doctors["name"]?></td>
        <td contenteditable="true" data-old_value="<?= $doctors["mob"]?>"
        onBlur="saveInlineEdit(this,'mob','<?=$doctors["id"]?>')"><?=$doctors["mob"]?></td>
        <td contenteditable="true" data-old_value="<?= $doctors["hours"]?>"
        onBlur="saveInlineEdit(this,'hours','<?= $doctors["id"]?>')"><?=$doctors["hours"]?></td>
    </tr>

<?php endforeach ?>

</table>

And this is php file to update data:

<?php
require("../includes/config.php"); 
CS50::("UPDATE doctors SET ".$_REQUEST["column"]."='".$_REQUEST["value"]."' WHERE  id='".$_REQUEST["id"]."'");
echo "saved";
?>

Thanks for help!

Oh... I've missed "query" in CS50::query. Works!
