Hello all thanks for reading, i'm having a issue with Angular Material md-select
it doesn't bind with my model. i'm using it to make a form to update data of this model.
<md-input-container class="md-icon md-block" flex ng-controller="ProveedorController" data-ng-init="listaProveedores()">
<label>Proveedor</label>
<md-select ng-model="detalle.proveedor" required name="proveedores">
<md-option ng-value="proveedor" ng-repeat="proveedor in proveedores">{{proveedor.nombreProveedor}}</md-option>
</md-select>
i've tried to use ng-selected
but it bind another object that doesn't fit with the original of the model.
any idea what i'm doing wrong?

I've experienced this first hand and attempted different solutions to no avail. The ultimate fix was using a controller instance variable instead of $scope to hold the ng-model value.
Instead of referencing $scope.somemodel
to retrieve the updated model value, use this.somemodel
.

Ok, after a good sleep and hours of searching i've found the solution of this.
to keep track of the objects i need to add a property on my md-select
in this case something similar to this: ng-model-options="{trackBy: '$value.id'}"
<md-input-container class="md-icon md-block" flex ng-controller="ProveedorController" data-ng-init="listaProveedores()">
<label>Proveedor</label>
<md-select ng-model="detalle.proveedor" required name="proveedores" ng-model-options="{trackBy: '$value.idProveedor'}">
<md-option ng-value="proveedor" ng-repeat="proveedor in proveedores">{{proveedor.nombreProveedor}}</md-option>
</md-select>
</md-input-container>
now all my models are display fine. Thank you for reading and sorry if i waste your time.

Markup
<div ng-app="MyApp" ng-controller="ProveedorController">
<md-input-container class="md-icon md-block" flex data-ng-init="listaProveedores()">
<label>Proveedor</label>
<md-select ng-model="detalle.proveedor" required name="proveedores">
<md-option ng-value="proveedor.nombreProveedor" ng-repeat="proveedor in proveedores">
