javascript - angular-slick attributes with capital case -

i making carousel angular-slick (https://github.com/vasyabigi/angular-slick).

some of slick settings carousel not seem work when used attributes of slick-directive. these attributes have 1 or more capital case letters.

i had change these attributes lower case letters in slick.js , in angular model slick.js. instance custom button next , previous had change prevarrow , nextarrow prevarrow , nextarrow can use in following way:

<slick  prevarrow='.btn-prev' nextarrow='.btn-next' arrows="true" data="windows">     <div ng-repeat="window in windows" class="slick-slide">         <a><img ng-src={{window.imageurls[0]}}></a>     </div> </slick>     <div class="slider-controls">      <button class="btn-next">customnext</button>      <button class="btn-prev">customprev</button> </div> 

changing code in libraries not seem right way working. there obvious mistake made or limitation slick-settings 1 can use via slick element ?

when see directives capital case nextarrow, must use them as

next-arrow 

no need change library code. angular follows same convention css. when there capital cased directive prevarrow, in html if want reference it, use prev-arrow.

best example is:

ng-app 

in html might have used ng-app if check in angular code, ngapp
