I want to hide a raw-input - angularjs

Question

I try to hide a row-input using ng-show but doesn't work. The field works in cascade with form.purchase:
- The field is visible if form.achat = R (Renewal)
- The field is empty and masked if form.buy = N (New)
this is my html code:
<div class="form-group mode-update col-md-10 no-padding">
<label class="col-md-4 control-label font-normal"> {{
'field.investissement.nouveauRenouvellement' | translate }} </label>
<div class="col-md-8">
<div class="form-group mode-update col-md-12
no-padding">
<div class="radio-inline">
<label for="achatBudgetTrue">
<input ng-
disabled="disabledField" ng-checked="true" type="radio" ng-true-
value="A" ng-false-value="B" name="achatBudget" value="N" ng-
model="entity.achatBudget" id="achatBudgetTrue"{{
'field.investissement.achatBudget.nouveau' | translate }}
</label>
</div>
<div class="radio-inline">
<label for="achatBudgetFalse">
<input ng-change="operations.changeEntityField"
ng-disabled="disabledField" type="radio" name="achatBudget" value="R"
ng-model="entity.achatBudget" id="achatBudgetFalse">
{{
'field.investissement.achatBudget.renouvellement' | translate }}
</label>
</div>
</div>
</div>
</div>
<raw-input
property="field"
vertical="true"
ng-repeat="field in fields | updateParams:metadata |
filter : { fieldSet : 'fieldset.investissement.descriptif'} | filter : {
name : 'parcAncienBudget' }"
entity="entity"
on-update="operations.updateEntityField"
on-change="operations.changeEntityField"
metadata="metadata"
ng-show="entity.achatBudget =='R'"
mode="update"
ng-show = "false"
creating="creating"
style="{inputSize: 'col-md-10 no-padding'}">
</raw-input>

Answer 1

You have two times an ng-show-attribute in your attributes:
<raw-input
...
ng-show="entity.achatBudget =='R'"
...
ng-show = "false"
The value of the second overrides the value of the first, so the element is never shown, no matter what value entity.achatBudget has.

Answer 2

I add a function in js:
$scope.isBudgetAchatVisible = false;
$scope.ShowParc= function(value) {
$scope.isBudgetAchatVisible = (value == "R") ? true : false;
}
and in the view:
<div class="radio-inline">
<input ng-checked="true" ng-change="ShowParc('N')" ............... >
</div>
<input ng-change="ShowParc('R')".....................>
</div>
<raw-input
ng-if="isBudgetAchatVisible
..............
</raw-input>
