javascript - ExtJS sort grid column of string as float -


i have grid column renders float record field string. so, when sort column, it's sorted string format , therefore, in wrong way:

enter image description here

i've tried different solutions. 1 understand should works use of sorttype function. haven't bee able far...

these important pieces of code.

my model load grid data:

ext.define('ama.model.assetmodel', { extend: 'ext.data.model',  fields: [     {name: 'account', type: 'string'},     {name: 'altlabel'},     {name: 'amortizable', type: 'int'},     {name: 'amortizationsvnc',         type: 'float',         convert: function(value,model){             return parsefloat(math.round(value * 100) / 100).tofixed(2);         }     },     {name: 'assetsaccountingprice',         type: 'float',         convert: function(value,model){             return parsefloat(math.round(value * 100) / 100).tofixed(2);         }     },     .....

my grid columns affected:

items: [{ xtype: 'grid', reference:'grdgestion', id:'grdgestion', //store: assetsstore, //height: ext.getcmp('maincontenedor').lastbox.height-150-50, columns: [{     .....      },{         text: l10n.translate('coste'),         flex: 1,         sortable: true,         dataindex: 'assetsaccountingprice',         xtype: 'numbercolumn',         decimalprecision: 2,         decimalseparation: ',',         thousandseparation: '.'     }, {         text: l10n.translate('vnc'),         flex: 1,         sortable: true,         dataindex: 'amortizationsvnc',         renderer: function(value){              return ext.util.format.number(value, '0,000.00');         }     }, {     .....

neither of 2 coumns sort data expected.

note (maybe useful): string format "0.000,00"

how can solve this?

please see this: fiddle

{     name:'fieldname',      type: 'float',      sorttype: 'asfloat', // need add      convert: function(value,model) {         return parsefloat(math.round(value * 100) / 100).tofixed(2);     } }
