Try this:-

$("#prgrp").keypress(function (e) {
     if (e.keyCode == 59) {
         //Call your function here
     }
});

Please note, you can also use e.which in place of e.keyCode as it is jquery standardized.

var code = e.keyCode || e.which;

try this code

$( "#prgrp" ).keypress(function( event ) {
    if ( event.which == 59 || event.keycode == 59 ) {
        //your function call
    }
});
