AngularJS conditional ng-disabled does not re-enable

Question

Given a conditionally disabled text input field using ng-disabled=\"truthy_scope_variable\", AngularJS disables the field the first time the scope variable

That's because HTML attributes are always strings, so in your example ngDisabled is evaluating a string in both cases ("true" or "false").

To remedy, you should compare the model against the string value in ngDisabled:

ng-disabled="new_account == 'false'"

... or use a checkbox, to get the actual boolean value:
