angularjs - add remove required validation in angular dynamically in angular js -

i have form shown below, have kept 1 field here simplicity. in form have many other fields including country dropdown. if country selected a,b or c want remove required validation using addressrequired gets true/false value on alter of country.

i removing required using .removeattr() , remove html.

but ng-disabled="myabcform.$invalid" stills shows invalid.

<form name="myabcform" ng-submit="submitform(myabcform.$valid)" novalidate class="myabcform"> <div class="element-box fltlt"> <label>address </label><sup ng-show="addressrequired">*</sup> <input type="text" value="" ng-model="details.address" required=""> <span ng-show="!details.address && addressrequired" class="error-msg field-validation-error">address required.</span> </div> <div id="clearfix"> <input type="submit" value="update" class="btn fltlt btnbg" ng-disabled="myabcform.$invalid" /> </div> </form>

any suggestions ?

use ngrequired instead, like:

ng-required="checkcountry()"
