html - Razor boolean html5 attribute being capitalised prevented conditional statements in jquery -

i have razor view with:

<select id="roletypeddl" >    <option value="@roletype.id" selected="selected" data-assignabletoperson="@roletype.assignabletoperson" >@roletype.name</option> </select> 

so in jquery wanted run code if data-assignabletoperson true hence:

if ($('#roletypeddl').find('option:selected').data('assignabletoperson') == true) {   } 

trouble code never getting executed.

i figure has html being produced being:

<select id="roletypeddl">   <option data-assignabletoperson="true" selected="selected" value="5">manufacturer</option> </select> 

i think problem "true" capitalised. know how around this?

data- attribute not know data type. @roletype.assignabletoperson html output true, not bool value, string...

following statement

data-assignabletoperson="true" 

is not bool value, string, should compare this:

if ($('#roletypeddl').find('option:selected').data('assignabletoperson') == "true") {     } 

update: data knows data type. problem "true". must "true".

and example
