How to add "if" condition in ember 1.10 HBS for #each

Hi I want to select the current month as default in the below code in Ember 1.10, current month is a variable in the controller:

currentMonth: moment().format("M"),
allMonths: moment.months()

////// HBS ////////////

<select id="selectMonth">
    
        
            <option selected="selected" value=''></option>   
        
            <option value=''></option>
        
    
</select>   

I am getting Error for this. what is the other way we can add a if condition in this scenario.
