php - Jquery function doesen't work when I change page/row or when I search some specific -

i made jquery function 1 deletes row selected. know option exist in datatables option, want myself, because prefer not use ajax, jquery , json. problem appears when search specify row in datatable search option, click button delete, , nothing happens. other mistake when click next page, then, rows page not work either.

do guys know be?

here let jquery function:

$(document).ready(function() {         $( ".botfactura" ).click(function(e) {     alert("jkn");     idfact = this.id;     var confirmacio = confirm("segur que vol esborrar la factura "+idfact);     /*if(confirmacio){         $.post("operacions/borrafact.php", {idfact: idfact}, null, "json").done(function(data){             alert(data.missatge);         })     }*/ });}); 

then, have json file there:

<?php   include("../connexio.php");  $idfact= $_post['idfact'];  $arraydatos = array();    if($idfact!=""){      $borrar = 'delete factures id="'.$idfact.'"';     //$connborr = mysqli_query($conn,$borrar);      $arraydatos['missatge'] = "factura ".$idfact." esborrada!";     }else{     $arraydatos['missatge'] = "no s'ha trobat";   }    echo json_encode($arraydatos);   ?> 

i call $(".botfactura") there:

<button type="button" name="<?php echo $line2['id']?>" id="<?php echo line2['id']?>" class="btn btn-danger botfactura"> <span class="glyphicon glyphicon-trash"></span> </button>    <button type="button" name="<?php echo $line2['id']?>" id="<?php echo $line2['id']?>" class="btn btn-success botfactura">  <span class="glyphicon glyphicon-pencil"></span>   </button>    

finally, i'll upload graphical example what's problem: :the first one, when page works correctly

then,the first issue appears when: i change page of table. can see, click , nothing happens

the same issue appears when try search specific row search box.

well, appreciate if explain why not working! thank you!

i don't know version of jquery using if jquery 1.9 or upper version try

$( document ).on('click', '.botfactura', function(e) 

or if using lower version try

$( ".botfactura" ).live('click', function(e)
