Cycle through input fields - html

Question

I have a table which I'm populating with some data I get from a database query
Table example
<tr ng-repeat="row in reservasTable">
<td> {{row.L}} </td>
<td> {{row.number}} </td>
<td> {{row.line}} </td>
<td> {{row.cod_art}} </td>
<td> {{row.creation_date}} </td>
<td> {{row.deadline}} </td>
<td> {{row.qtt_ordered}} </td>
<td> {{row.qtt_delivered}} </td>
<td> {{row.ocor}} </td>
<td> <input type="text" id="qttField" ng-model-onblur ng-model="qtt" ui-keypress="{13:'setQtt($event)'}">
</tr>
The only field I don't get from the JSON query is the last one, an input field which is used to fill with a certain amount (Quantity).
What I need to do is: after I fill whatever fields I want, (e.g., the 1st, 4rd and last) I need to cycle through those fields, check which ones are filled and get the value from them.
I can't seem to get the value just from the model, since the model is the same for every field, that's why I'm currently using the 'Enter' button to update the value and send it to an array:
Simple Version:
$scope.arrayQtt = [];
var i = 0;
$scope.setQtt = function(evt){
$scope.arrayQtt[i] = evt.srcElement.value;
i++;
};
It is preferable to check all input fields with a 'Confirmation' button, after all fields are filled, since an user can edit a field the amount of times he wants before clicking the 'Confirmation' button.
Any help, advice or guidance is appreciated.
Thanks in advance!
