when editing value image not getting updated ,cant understand why ? either should happen on clicking button image should automatically turn red,any of solutions appreciated. in adcvance.

the modal turns items.sa string, no branches in imagefilter match anymore because sa compared numeric values only.

two solutions spring mind:

use number input box: <input type="number" data-ng-model="items.sa"/>

or

coerce sa number in imagefilter:

app.filter('imagefilter', function () {     return function (sa) {         sa = +sa; //coerce sa number         if (sa === 0) {         ....
