Angularjs and select default value - angularjs

Question

I have this HTML code (no, I can not to convert it in a ng-options):
<form>
<div class="list">
<div style="margin-bottom: 20px;">
<label class="item item-input item-select">
<div class="input-label">
Price From (start)
</div>
<select required id="priceForm" ng-model="search.priceFrom" ng-init="'search.priceFrom = searchParams.priceFrom'">
<option value=0>All</option>
<option value="100">100</option>
<option value="200">200</option>
<option value="500">500</option>
<option value="700">700</option>
<option value="1000">1000</option>
<option value="1500">1500</option>
<option value="2000">2000+</option>
</select>
</label>
</div>
<div>
<label class="item item-input item-select">
<div class="input-label">
Vacation Days (start)
</div>
<select required ng-model="search.vacationDays">
<option value=0 >All</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
<option value="6">6</option>
<option value="7">7</option>
<option value="8">8</option>
<option value="9">9</option>
<option value="10">10+</option>
</select>
</label>
</div>
</div>
</form>
I want this:
The first time that I see this page the values of both select must be "All" (value = 0), and I think that I need only to add "required" but it does no work.
And for every next times the default value need to be the value inside searchParams.priceFrom (it is a variable in my $scope).
Where is my error ?
Thanks.

Answer 1

Since both selects are bound to your search.vacationDays && search.priceFrom all you would need to do in your controller is something like:
$scope.search.priceFrom = 0;
$scope.search.vacationDatys = 0;

Answer 2

Please see demo below
just set your serach obj in controller
$scope.search = {
priceFrom: 0,
vacationDays: 0
}
var app = angular.module('app', []);
app.controller('fCtrl', function($scope) {
$scope.search = {
priceFrom: 0,
vacationDays: 0
}
});

<div ng-app="app">
<div ng-controller="fCtrl">
