ng-model removes the display of the standard value from input'a, help fix

Question

<input type="number" name="width" step="10" value="4000" ng-model="widthM">

Apparently, you need to replace value="4000" with ng-init="widthM=4000"
@Yaant the same question arose for the radio and checkbox <label class="radio-inline"> <input type="radio" name="type" ng-init="sum=false" ng-model="sum"> buttons <label class="radio-inline"> <input type="radio" name="type" ng-init="sum=false" ng-model="sum"> !!!!!!!!!!
<label class="checkbox"><input type="checkbox" name="type2" value="{{calc.products.gate}}" ng-model="gateM" ng-true-value="{{calc.products.gate}}" ng-false-value="0"> Калитка</label>
