AngularJS copy value to another input on fly

Question

I need to bind 1 model to 2 inputs. First input should be visible and i use it to set value to model

<input type="text" ng-model="ttl" class="form-control input-sm"/>

Second input hidden and i use it for form. I need to keep here actual value of model

<input type="text" name="ttl" value="{{ttl}}" class="form-control input-sm"/>

The problem is hidden input always empty.... How to fix it? Thanks.

Try ng-value not value maybe.

This seems to work for me (second input box only below):

<input type="text" name="ttl" ng-value="ttl" class="form-control input-sm"/>

or

<input type="text" name="ttl" ng-model="ttl" class="form-control input-sm"/>

I understand that you will hide that input yourself?

After I put copy-field under ng-model field in html it works.... But is there any way to put copy field before ng-model? Is order so important?

@Anton Abramov Sorry, not sure what u mean? If you ask about the order of input elements in the DOM then it shouldnt matter no.

I mean when i try to fill first field, value copies to second. But if i try to fill second field, first doesn't change

@Anton Abramov If you use ng-value for second then it wont change. But you can put ng-model in both which will work then. But I though the second element will be hidden anyway so you wont be able to input anything?

Funny thing - actually in my project hidden field will be in form(right now it's not hidden for testing). Ng-model field will be under the form in div. So in that order field in form empty if i fill field in div, but if i fill form-field div-field will change value.

Simple use ng-model on both:-

 <input type="text" ng-model="ttl" class="form-control input-sm"/>
    <input type="text" name="ttl" ng-model="ttl" class="form-control input-sm"/>

Sorry, but problem is not about hiding. I use type="text" here for example. Problem is about copy value from one field to another
