Blazor select onchange event value not changed

I have a <select> inside my Razor View. I'm trying to save the selected option in the database whenever the selection is changed.

I'm able to do it with an <input type="text"> or any type of input, but my select doesn't work.

Here is the code :

<select name="expression@(i)"
@onchange="@(async e =>
{
    // Test is always equals to "1", which is the old value of the select
    var test = e.Value.ToString());
    
    //Do Stuff
})">
@foreach (var expression in (ExpressionEnum[])Enum.GetValues(typeof(ExpressionEnum)))
{
    <option value="@((int)actionItem.ExpressionEnum)" selected=@(expression == actionItem.ExpressionEnum)>
        @expression.ToString()
    </option>
}
</select>

As commented, the selected option of the select is actually the first one, "1".

But even if I try to select another one like the "5", the test variable will remains equal to "1".

How can I get the correct selected value ?

actionItem.ExpressionEnum does not seem to change during the loop which sets value to, what I assume to be, 1 for every option in your <select>.

I believe you should change this part:

value="@((int)actionItem.ExpressionEnum)"

to

value="@expression"
