How to Customise the angular material date-picker?

Question

I am using the material design date picker

<md-content flex class="padding-top-0 padding-bottom-0" layout="row">
                <md-datepicker ng-model="user.submissionDate" md-placeholder="Start date" flex ng-click="ctrl.openCalendarPane($event)"></md-datepicker>
                <md-datepicker ng-model="user.submissionDate" md-placeholder="Due date" flex></md-datepicker>
            </md-content>

and its shows the UI like this

I want to remove the calendar icon and include the ng-click functionality in the input box.

How to bind the runtime event with the input box?

css

<style>
 .inputdemoBasicUsage .md-datepicker-button {
    width: 36px; }
    .inputdemoBasicUsage .md-datepicker-input-container {
    margin-left: 2px;
  }
    .md-datepicker-input-container{
    display:block;
    }
    .md-datepicker-input[placeholder]{
        color=red;
    }

    .padding-top-0{
    padding-top:0px;}

    .padding-bottom-0{
    padding-bottom:0px;
    }
</style>

Additional to @EmirMarques answer, I wanted to make the input field read only. so i added this code. Here user can't edit the date input field. so its

Better One

$scope.initDatepicker = function(){
        angular.element(".md-datepicker-button").each(function(){
            var el = this;
            var ip = angular.element(el).parent().find("input").bind('click', function(e){
                angular.element(el).click();
            });
            angular.element(el).parent().find("input").prop('readonly', true);
            angular.element(this).css('visibility', 'hidden');
        });
};

And this CSS made the look better

.md-datepicker-input-container {
    display: block;
    margin-left: 0 !important;
    width: 100% !important;;
}
