Using angular ng-repeat in UI Action GlideModal

[davilu]

Our team is trying to build an UI Action on case records that brings up a modal with dropdown of selectable email addresses.  The dropdown of email addresses should include users who have the HR user skill.  Is there a way to use ng-repeat to loop through an array of users in this dropdown?  If we can't use angular ng-repeat, is there another way to achieve this?

Here is the client side script we have so far:

function emailHC() { 
var gm = new GlideModal('emailHCModal'); 
gm.setTitle('Email HC'); 
var str = '<div style="padding:15px">' + 
'<p>' + 
'<select name="tagging" id="tagPopUp" class="form-control">' + 
'<option ng-repeat="x in getUsers()" value="{{x.name}}" role="option">{{x.email}}</option>' + 
'</select>' + 
'</p>' + 
'<p>' + 
'<label for="commentTextArea">Reasons for Emailing TSA Human Capital</label>' + 
'<textarea class="form-control" id="commentTextArea" rows="3"></textarea>' + 
'</p>' + 
'<div style="padding:5px;float:right">' + 
'<button style="padding:5px;margin-right:10px" class="btn btn-primary" onclick="window.reasonForReturnTaskAction(this.innerHTML,jQuery(\'#commentTextArea\').val())">Enter</button>' + 
'<button style="padding:5px" class="btn btn-default" onclick="window.reasonForReturnTaskAction(this.innerHTML,\'\')">Cancel</button>' + 
'</div>' + 
'</div>' 
gm.renderWithContent(str); 
window.reasonForReturnTaskAction = function(thisButton, commentText) { 
if (thisButton == 'Cancel') { 
gm.destroy(); 
} else if (thisButton == 'Enter') { 
if (commentText == '') {
alert('Reasons for Emailing TSA Human Capital are required.'); 
} else { 
gm.destroy(); 
g_form.setValue('work_notes', 'Reasons for Emailing TSA Human Capital: ' + commentText); 
gsftSubmit(null, g_form.getFormElement(), 'email_hc'); 
} 
} 
}; 
return false;
}

 Here is the server side:

if (typeof window == 'undefined') { 
updateTask(); 
} 

function updateTask() { 
current.update(); 
var hcscQaService = new sn_hr_core.hcscQaService; 
var processedBy = gs.getUser().getID(); 
hcscQaService.routeToHcExecutives(current, processedBy); 
}

function getUsers() { 
var arr = []; 
var gr = new GlideRecord('sys_user_has_skill'); 
gr.addEncodedQuery('active=true^skill.name=HR'); 
gr.query(); 
while (gr.next()) { 
var user_sysID = gr.user.getRefRecord(); 
arr.push({ 
name: gr.getDisplayValue('user'), 
email: user_sysID.email 
}); 
}
return arr; 
}
