jquery - Custom renderer function not working in handsontable plugin -

i have function handles onchange events , works well. function calls 1 check contents of cell, , if there wrong should change cell color.

function check(x, y) {     var content =   $editortablecontainer.handsontable('getdataatcell', y, x);     var split   =   content.split(' ');          $.each(split, function (key, value) {         $.get('check.php?word=' + value, function (data) {             //blank if no error otherwise returns array of suggestions (only need check if there error)             if (data) {                 alert("test");                 var meta = $editortablecontainer.handsontable('getcellmeta', y, x);                 meta.renderer = errorrenderer;             }         });     });      return; } 

and here simple errorrenderer:

function errorrenderer(instance, td, row, col, prop, value, cellproperties) {   handsontable.textcell.renderer.apply(this, arguments);   console.log(row);   td.style.fontweight = 'bold';   td.style.color = 'green';   td.style.background = '#cec'; } 

the errorrenderer never called, eventhough alert triggered, idea why?

thank you

if using handsontable, why don't use built in functionality?

have @ hts conditional formatting

also, in version 0.9.5 column option added validator. details here.

validator (value: mixed, callback: function)  

or

validator : regexp object 

then using event (details here):

aftervalidate (isvalid: boolean, value: mixed, row: number, prop: string, source: string)  

do formatting of cell

also, in example, setting renderer, cell being rendered? need re-render?
